Measurement ranges
The EM4058 automatically selects an adequate range when operating, allowing measurements
between 0.01 Ω and 20 kΩ (resistance), 0.01 Ωm and 50 kΩm (resistivity), or voltages between 0
and 60 V~ (when in the voltmeter function).
„ Equipment calibration checking
By using a standard resistance (Rx), it is possible to test the equipment calibration. The resistance
must be connected to the EM4058 as shown below:
After connecting the resistance, follow these procedures:
1.
Turn the EM4058 on (
2.
Select the resistivity function (
3.
In the distance / standard resistance selection function(
standard resistance).
4.
Press the
key.
5.
After 5 seconds, a stable value close to the standard resistance's nominal value should
appear on the display. If this is not the case, the equipment accuracy is out of its
specification and must be adjusted by a qualified laboratory.
