Thank you for choosing Velleman! Please read the manual thoroughly before bringing this device into service. If
the device was damaged in transit, don't install or use it and contact your dealer.
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. 12 V/100 mA.
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.
