GE K400 user manual Calibration of the resistance Ohm input ranges DBC-TC only

Page 62

Nominal Value is the recommended value for the test): pressing the ent key causes the microprocessor to combine the current indications on the display (True Value and Effective Reading).

•Calibration of the resistance (Ohm) input ranges (DBC-TC only)

As for the millivolt input range, also the resistance measurement channel has different ranges capability, depending on the RTD measurement available.

CALIBRATION

Ohms INPUT

1 KOhms INPUT

From the CALIBRATION menu select the required Ohms input range to be

calibrated, using the keys, and press ent.

Ohms INPUT

Nominal value:

300Ω

True value: 300.00Ω

Reading: 298.00Ω

Press ENT or CE ...

Using a certified and high accuracy Ohms simulator, apply the required value to the related electrical connection on the front panel of the instrument (the nominal value is the recommended value for the test).

Pressing the ent key causes the microprocessor to combine the resistance measure on the display (true value and effective reading).
