Introducing the RS PRO Current and Voltage Calibrator that offers outstanding performance, durability and reliability. This rugged calibration tool from RS PRO is compact, lightweight, and easy to carry and offers a push-button interface that is ergonomic and easy to use. It is EMI tolerant, dust and splash resistant, and features a removable battery door for quick battery changes. This unit is a precision source for calibrating process devices and offers a high level of accuracy and versatility across a wide range of applications for an affordable price.

• The RS PRO current and voltage calibration unit works as a multifunction calibrator and an arbitrary function generator
• This unit offers a unique mapping function that lets you calibrate temperature (300 °C) or voltage (220 V) directly (instead of 4 to 20 mA indirectly)
• It can simulate a current transmitter and make measurement and output loop power 24 V (LOOP+) simultaneously
• The clear and easy to use interface offers a numerical keypad with a sliding switch and a dot matrix LCM that’s backlit so it can be used in low-light applications if needed
• This calibration unit can perform data logging with programmable sampling time (0-255 seconds) and memory of 4000 records
• The calibration results (source and measure) can be saved in memory (2000 records) and the user can download them to a PC for documentation, meaning there is no need to transcribe calibration data manually
• The calibration unit offers DTMF (Dual Tone Multi-Frequency) which can perform professional testing for telephone lines and audio products (MP3 or MD)
• The programmable cold junction compensation feature allows users to fine-tune temperature output and measurement
• Voltage, frequency, PWM duty-cycle (square wave and triangular wave), and offset are programmable in the Hz function
• The auto-step and auto-ramp functions can quickly perform a linear test
• The device offers user-selectable HARTTM resistor to facilitate use with HARTTM communication devices
• The short circuit protection for voltage output ensures the calibration unit is protected
• It is powered by a rechargeable Lithium battery (1600 mAH) with a built-in charging circuit

• Electronic load (max. 30 V, 24 mA)
• 4-20 mA (open voltage 24 V) direct source mode
• Source: mA (4 to 20 mA), V (0 to 15 V, 0 to 70 mV), Hz, sine wave, square wave, triangular wave, truncated sine wave, user-programmable waveform and temperature for 11 types of thermocouples
• Measure: Current (mA), Voltage (V, mV) and temperature in °C or °F
• Frequency range (0.3 Hz to 20 kHz) covers the application of audio band (speaker, MP3, MD, etc.)

A current and voltage calibrator is a device that can be used as a general-purpose current and voltage source. Their high performance and easy operation make it suitable for test engineers, R&D, service, and calibration technicians to use. A calibrator is an essential piece of equipment in any electronics workshop, any test and measurement department, in industry and automation. The most common applications include maintenance operations, commissioning, verification, on-line calibration and adjustment and testing of measurement lines and a good portable current and voltage calibrator can be a crucial tool for those working in field calibration, testing and troubleshooting of panel meters, transducers, transmitters, actuators and other process and control devices.
