High resistance calibrator for insulation testers up to 10 kV. Other insulation related functions include HV capacitance, short current, dielectric and polarization parameters and timer test.

• Six different calibration functions
• 1 TΩ and 10 kVdc limits
• Test voltage and current indication

M191 Insulation Tester Calibrator is based on 1 TΩ programmable high resistance decade with 10 kV DC compliance, coupled with test voltage meter. This setup allows for calibration of UUT's test voltage, short current verification, timer function verification and calibration of dielectric parameters measurement including polarization index (PI), dielectric absorption ratio (DAR) and polarization ratio (PR).

Calibration domain

M191 is designed for thorough calibration of insulation testers, megaohmmeters, HIPOT testers or any other DC high resistance meters and safety testers with test voltage up to 10 kV. With M191's pallete of functions you'll no longer need multiple instruments and complex setups for high voltage calibrations.

3000W power load based on Real-Resistance decade design with built-in multimeter for simulation of constant power and constant current functions.

• Maximum load 3 kW and 250 Vrms
• Real resistance function
• Temperature coefficient < 10 ppm/°C
• German included

M192 is accurate high-power resistance decade for testing of power supplies and batteries up to 3000 W and 250 Vrms. Being a resistance decade rather than an electronic load, resistance function uses real resistance so it can be used with AC power sources as well. See datasheet for typical frequency responses. On top of that, M192A version has built-in test signal meter using which constant power and constant current functions can be simulated. Other advantages of the M192A are extended range up to 300 kΩ and continuous resistance range rather than fixed values.

First generation programmable capacitance decade with RS232 interface and internal battery for up to 3 hours of on- site calibration.

• 0.25% accuracy, maximum voltage 50 V
• Battery-powered
• Remote control via RS232 bus

M520 Programmable Capacitance Decade is designed specifially for calibration of capacitance ranges of multimeters and RCL meters. As a predecessor of M525, the M520 is very similar in circuitry, providing same accuracy and comparable parameters for less. Sturdy mechanical knob design makes manual control pretty straightforward along with internal rechargeable battery make the M520 ideal for on site calibrations where grid power is not an option.

Connectivity

Even though the M520 looks mechanical, internal capacitance standards are switched electronically by relays. This way we could fit it with RS232 remote control so it can be used in Caliber or any other automated calibration solution.

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.
