Three- or single-phase electric power/energy calibrator with power quality functions for calibration and testing of grid measuring appliance like power meters, power transducers or power quality analysers.

• Power quality and energy functions
• 0.02° phase shift accuracy
• 15 - 1000 Hz output
• Built-in multimeter for transducer calibration
• Floating current outputs for 3-wire power meters
• Chinese included

M133C is electric AC/DC power and energy calibrator for calibration of power meters, power transducers, power quality analysers and generally all kinds of power measuring devices. AC voltage, current, power and energy functions have calibrated phase shift in frequency range from 15 Hz to 1 kHz with resolution as good as 0.001 Hz. Simulated electric power (including power quality functions) can be set independently in each phase of both voltage and current signals. Built-in 5½ process multimeter for transducer calibration is standard part of every M133C calibrator.

Languages: English, Chinese (simplified)

Power quality functions

Four different distortion functions are available in M133C calibrator: Harmonic distortion with up to 50 harmonic products, interharmonic distortion up to 5000 Hz, amplitude modulation using symetrical sine or square wave envelope and finally dip/swell amplitude modulation using custom square wave envelope. Modulation frequency can be set in range from 0.001 Hz to 50 Hz, maximum modulation depth is 30 % and again, all the distortion parameters can be set independently for each phase.

Calibration versatility

M133C is more than just a sophisticated power source. Using built-in process multimeter, both transducer inputs and outputs can be handled by the M133C at the same time so you can calibrate it more easily, using no other calibration equipment. Floating current outputs can be connected directly with voltage outputs to allow for 3-wire power meter calibration. One calibrator, many applications - saving your time, space and costs.

Series of single resistance standards designed specifically for RCL meters up to 100 MHz.

• Frequency rating 100 MHz
• Very low frequency dependency

M530 series is designed specifically for calibration of LCR meters in frequency range from DC to 100 MHz, thanks to its HF design and using strip line technology. Four-pair BNC terminal connection with 22 mm distance can be connected directly to UUT without additional test leads.

Bank of fixed resistance, capacitance and inductance standards with defined frequency characteristic up to 1 MHz for automated calibration of RCL meters.

• Automated RCL calibration
• Calibration data from 20 Hz to 1 MHz

No need for pen and paper method

Idea behind M550 Impedance Calibrator is to replace countless single value RCL standards with one calibrator that can switch between the standards like a CD changer in your car. The calibrator contains stable and temperature independent resistance standards, partial capacitance standards and partial inductance standards, simulated by RC T-type passive network. Calibration values of both complex parameters of partial standards are displayed on large LCD screen in preselected pairs of parameters as well as voltage, current and frequency readouts from built-in test signal meter. OPEN and SHORT reference positions are available as well.
Easy recalibration system offers either full recalibration in all spot frequency points or simplified offset calibration. History of calibration values of partial standards at reference frequency 1 kHz can be easily recalled.

Calibration domain

M550 was designed for calibration of RCL meters in frequency range up to 1 MHz. The philosophy of M550 is based on remote control and automated calibration. For this reason, the calibrator is equipped with RS-232 and GPIB interfaces and of course, supported in CALIBER/WinQbase calibration software

Still demanded by some of our customers, these older decades provide similar ranges and accuracies while being more economical then their latest counterparts.

Similar to current M63x and M64x Real-Resistance series, these decades provide high accuracy and resolution over continuous resistance range. As opposed to latest models, user of legacy decades might be missing large dot-matrix LCD display, improved AC characteristics, free/cheaper options, timing function, USB and LAN interfaces, SCPI command support and other minor improvements. On the other hand, legacy decades are a bit more economical and can be battery operated.

Resistance decades designed for RTD and other resistance-based sensors simulation. Operated either manually or via one of four available remote-control interfaces these decades are ideal for automated checks at production lines.

• Real resistors switched by relays
• Custom temperature scales
• No residual resistance
• 0.01°C accuracy
• Six different languages

M631 and M641 are programmable real-resistance decades with parameters designed specifically for RTD sensors' simulation and testing of RTD evaluation units like temperature regulators, transducers, etc. The core function is still resistance so you can as well calibrate ohmmeters and other resistance based meters easily. The main difference between M6x1 RTD simulators is combination of accuracy and load capacity. M641 with its 5 W load capacity is suited for industry where M631 with its 0.01°C accuracy and 0.001°C resolution is rather a laboratory reference. Containing some of the most stable (and expensive) foil resistors available, the M631 has temperature coefficient as good as 1 ppm/°C. RTD simulators can be used for AC application as well, see datasheet for typical frequency responses.

Languages: English, German, Spanish, French, Russian, Czech

User comfort

M6xx series was made to make resistance calibration as easy as it gets. Large LCD shows all related parameters including total accuracy. And there is no residual resistance or hidden absolute error so you don't have to calculate it by yourself, accuracy you see is accuracy you get. And that's not the only thing that firmware sorts out for you. Would you like the resistance shown in distance or force units? User function will do this for you. Complete recalibration? Ten minutes and off you go.

Connectivity

RTD simulators' functions can be remotely controlled via RS232, USB, LAN or GPIB interface. This way you can introduce calibration/test stage directly into production line of any resistance based sensor and reduce time required for final quality tests dramatically.

Resistance decades with ranges as wide as 14 decades. Sophisticated design and switching algorithm provides zero residual resistance, high accuracy and temperature stability for the most demanding applications

• Real resistors switched by relays
• 14-decade range, resolution from 1 μΩ
• Custom units and time sequences
• No residual resistance
• 20 ppm accuracy / 5 W load capacity
• Six different languages

M632 and M642 are programmable real-resistance decades with far-reaching ranges and very fine resolutions. While the M642 is rather an industrial decade with its 0.1 Ω - 20 MΩ range (22 MΩ upgrade available) and 5 W load capacity, the M632 is 20 ppm reference instrument for calibration laboratories and flagship of Meatest's resistance calibration. Containing some of the most stable (and expensive) foil resistors available, the M632 has just 1 ppm/°C temperature coefficient. Decades can be used for AC application as well, see datasheet for typical frequency responses.

User comfort

M6xx series was made to make resistance calibration as easy as it gets. Large LCD shows all related parameters including total accuracy. And there is no residual resistance or hidden absolute error so you don't have to calculate it by yourself, accuracy you see is what you get. And that's not the only thing that firmware sorts out for you. Would you like the resistance shown in temperature units? Distance? Force? RTD and user function will do this for you. Complete recalibration? Ten minutes and off you go.

Connectivity

All decades' functions can be remotely controlled via RS232, USB, LAN or GPIB interface. This way you can introduce calibration/test stage directly into production line of any resistance-based sensor and reduce time required for final quality tests dramatically.

35 ppm AC/DC multifunction calibrator for multimeters, ammeters, ohmmeters, temperature meters, transducers, regulators and many more. Built-in multimeter further increases user comfort by simultaneously reading and evaluating UUT output signals.

• Wide range of functions
• Built-in multimeter

Multifunction calibrator M140 is calibrator – tester for use in calibration laboratories as an electrical standard of voltage, current, resistance, capacity and frequency. Load capacity of the voltage output is 30 mA - enough for most high-consumption analogue power-meters. Installed harmonic and non-harmonic shape signals allow for testing meter sensitivity to distorted signals by a signal with various crest factor. Frequency modes, suitable for calibration of multimeters and time bases of oscilloscopes, have adjustable 6-digit frequency, amplitude and duty ratio of the output signal. The calibrator can measure temperature with TC and RTD temperature sensors to show it on display or use for cold junction compensation.

Built-in multimeter - Tester

Internal multimeter with basic capability to measure VDC, IDC, R and F process signals is standard part of M140 full version. Meter functions can run simultaneously with source functions to measure and evaluate output signals of various types of transducers as well as external sensors (strain gauge, pressure, torsion, strength, etc.).
Another useful feature of the multimeter is 10-point automated UUT test. The calibrator can be set to source an output signal in up to 10 predefined steps and compare UUT's output with predefined specifications and optionaly operate the UUT or a switch using a relay output. The results are then displayed directly on the calibrator screen in a comprehensive table with PASS/FAIL sign at each step.

User comfort

M140 calibrator is focused on user friendliness making calibrations simple and straightforward. Each function has its dedicated chunky button and all relevant details including total relative accuracy are shown on large LCD. Range of adapters for easier terminal connection and automation possibilities, relative deviation feature that can help you with UUT error calculation and easy keyboard-controlled adjustment procedure are just a few examples to prove the point.
GPIB and RS-232 interfaces are present in both versions so the calibrator can be operated via remote control or used in WinQbase/Caliber software calibration systems including the CamOCR module for automated optical UUT readouts.
