Fluke PRV240 Proving Unit

This proving unit comes pre-calibrated and is used to test instruments working with DC ad AC voltages. The device is compatible with both AC and DC supplies and can measure up to 240 volts. The device provides a fix 240 volts to the equipment and ensures the device under test is exactly calibrated at 240 volts. The device is also extremely useful in detecting and removing the extra voltages which lead to hazardous situations.

Features:

Ø  Supplies 240 V DC/AC

Ø  Single LED Indicates Functionality

Ø  High Impedance Or Low Impedance Compatible Testing Devices.

Ø  Accidental Contact Avoids Feature Through Recessed Contact

Ø  Long Battery Life

The "Test Before Touch" (TBT) definition or three-point test method involves measuring your device before and after the actual measurement against a known live source. Compared to verification of research instruments on high-energy sources in potentially dangerous electrical settings, the use of the PRV240 decreases the possibility of shock and arc flash since the PRV240 produces a defined voltage in a regulated, low-current condition in compliance with safe work practices.

AC/DC Measurement:

To test the device with following the steps below:

1-      Power On The Device.

2-      Turn The Switch To AC Or DC Depending Upon The Application Under Test.

3-      Place The Leads Into Positive And Negative Terminals Into The Device.

4-      If The LED Turns Green, The Device Under Test Is Calibrated.
