Handheld calibrator-multimeter of industrial process signals including voltage, current, resistance and temperature. External signals up to 200 V or 100 mA can be measured simultaneously with signal sourcing.

• Handheld calibrator and multimeter
• 1 ms sampling feature
• Datalogger option

The main functions are the sourcing of mV or mA signals, resistance and simulation of DIN-thermocouples and RTD temperature sensors. Up to eight fast input signals -Transients- can be measured, memorized and shown at the display as graphs or uploaded to a PC via USB. For fast checking or calibration of process transmitters the M505 output and input can be cross connected to the transmitter, whereas both sourced and measured signals will be displayed online. mV voltage ranges are useful for calibration of strain gauges, amplifiers, transmitters and small signal instruments, where the output voltage can be resolved down to 1 uV.

Datalogger (Option): The generated calibrator signal and the measured signal at the multimeter input will be stored as tables with date and time added. The interval is selectable from 2 sec. to 24h. The data can be transferred to a PC, shown as tables and graphics and handled under Windows and Excel.

Transients: Eight memory slots are available for storing of fast signals at the multimeter input. Each transient ca individually be shown at the LCD display and optional transferred to a PC, shown as tables and graphics and handled under Windows and Excel.

base version

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.

10 ppm AC/DC multifunction calibrator with built-in multimeter, 30 A extended current range and variety of functions to calibrate most of the instruments your electrical laboratory will ever come across with ease.

• 10 ppm accuracy
• 30 A range, variety of functions
• Built-in multimeter

Multifunction calibrator M142 is calibrator of electric quantities for application in calibration laboratories and in production lines where voltage, current, resistance, capacity and frequency meters are manufactured. 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

Built-in process multimeter, standard part of M142 full version, can be used independently or simultaneously with source functions which makes testing transducers, regulators and evaluation units really easy. Using a single instrument, you can evaluate output signals of various types of transducers and external sensors (strain gauge, pressure, torsion, strength, etc.), read them directly from calibrator display and use them in your calibrations.

User comfort

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.

65 ppm AC/DC multifunction calibrator with extended voltage range 0 to 1000 V, current range 0 to 20 A and other basic functions within ultra-portable, 9 kg body.

• Ultra-portable
• 1000 V and 20 A ranges
• 60 ppm accuracy

M143 Portable multifunction calibrator is cost saving solution for calibration of meters of electric quantities up to 1000 V and 20 A. Basic accuracy of 60 ppm in DC voltage is more than enough for calibration of 3½ and 4½ digit multimeters. Resistance function is covered by eight fix resistors in range from 10 Ω to 100 MΩ, other features are TC temperature sensor simulation and optionally RTD temperature sensor simulation. Thanks to its small dimensions and low weight the calibrator is ideal for field calibrations.

Calibration domain

M143 was designed for automated calibrations at production lines of panel meters, multimeters, transducers, measuring amplifiers, thermometers, and calibration laboratories where the calibrator can be applied as source of standard value for calibrations, verifications and adjustments of units under test.
RS-232 and optionally GPIB interface allow for remote control of the calibrator and time saving automated calibrations using SW package CALIBER/WinQbase.
