5. Equipment calibration checking

By using a standard resistance (Rx), it is possible to test the equipment
calibration. The resistance must be connected to the EM-4058 as shown
below:
After connecting the resistance, follow these procedures:
Turn the EM-4058 on (
·
Select the resistivity function (
