Proving Units

Used in combination with two-pole voltage testers to verify that they are safe for use both before and after testing periods.

A Portable lightweight unit with two integrated ports designed to house the probe tips of a voltage tester. Once the probes are inserted into these holes and the MPU690 is activated it will test voltage levels in five steps - 50, 100, 230, 400 and 690V. When each voltage passes the proving unit's tests an LED light will switch on on the front of the tester.

Designed to work automatically whenever its needed, the MPU690 will power on once testing probes are inserted into the unit and it will then simulate a 50Hz output voltage designed to represent AC mains supply.

The MPU690 is perfectly acceptable for use with other makes and models of two-pole voltage testers.

• 5 stepped nominal output voltages.

• High output power suitable for test lamps.

• Extended battery life, although the unit has a high output the unit has exceptionally good battery life.

• The rugged case of the MPU690 features a magnetic base for convenient use.

•N.B. The MPU690 is not recommended for use with multi- meters.

MPU690 2 Pole Proving Unit

This is a convenient pocket-sized, battery powered proving device that produces a 240V DC output. Any device used for voltage detection and for proving dead should be tested before and after use to ensure the safety of the operative. 
The PD240 current is limited to 2mA and is suitable for use with multimeters and other voltage detectors that have an input impedance greater than 120KΩ. It has a long battery life.

Features:
• Safely and simply proves the operation of multimeters and voltage testers
• 240V DC output proving unit
• Compact size with belt clip
• Essential for implementing effective safe isolation

A unique proving unit that comes complete with a CALCHECK feature for use with installation testers and 5 stepped voltage thresholds matched to common two pole tester thresholds. This additional feature makes it easy to verify the insulation and low resistance ranges on many multifunction and single function insulation testers on-site.

Features and Benefits:
•CALCHECK function is Ideal for identifying potential calibration issues with a multi-function tester prior to certifying a new wiring installation or carrying out a condition report
•Safely proves the operation of voltage indicators and test lamps up to 690V
•Long battery life and a low battery indicator

Typical Applications:
•Electrical installations and maintenance

PRV240
The Fluke PRV240 proving unit is a portable, pocket-sized, battery-powered voltage source. It is unique in that it sources stable AC and DC voltages for both LoZ and HiZ instruments. The PRV240 reduces the risk of shock and arc flash by removing unnecessary exposure to a potentially hazardous electrical environment while verifying the functionality of test tools before and after absence or presence of voltage is checked.

Output voltage: 240V AC RMS or DC (±10% ≥1MΩ). LoZ>3kΩ load (60V AC typical, 50V AC RMS minimum).
Operating temperature: -10°C to +50°C.
Safety: IEC61010-1, IEC61010-2-030.
