AVM52ERT – Analogue Earth Resistance Tester
1. Introduction & Features
Thank you for buying the AVM52ERT ! Please read the manual carefully before bringing this
device into service.
•
The modern design limits the influence of the earth voltage and the earth resistance of
auxiliary earth bars to a minimum.
•
Press the BATT.CHECK button to test the auxiliary earth resistance and the connection
cable. The OK lamp lights up when the device is ready to perform accurate earth resistance
measurements.
•
Low power consumption : max. 12V/100mA.
•
Push buttons allow smooth operation of the device.
•
The earth resistance value can be read directly from the scale.
•
You only need to press the SIMPLIFIED MEAS. button for simplified measurements. No
shorting wire is required since terminals P and C can be shorted internally simply by
pressing this button.
•
Battery replacement is easy.
•
The carrying case in hard plastic is water-resistant and accommodates all accessories.
