CONTINUITY TESTER EP 4Ex

The EP 4Ex is a digital display controller for measuring line resistances

electrical in areas at risk of explosion which can reach an insulation resistance

of 2000Kohm with a voltage of 500V.

 Usage:

- Connect the measurement lead to the device and to the line to be measured

- Switching on the device: press the ON/TEST key. The device goes into the

measurement mode and displays –1 or +1.

- To measure the line resistance, Press the  key until the

measurement is displayed (the measurement remains displayed for approximately 3 seconds). During the

measurement, the device sends a test current of 20 mA in the line.

- You can redo the measurement by inverting the measurement current: press the

+/- before measurement. This process makes it possible to check whether galvanic couples are

present and disrupt the measurement.

- When finished, press ON/TEST to turn off the unit. This one goes out

automatically after 20 seconds of non-use.
