EA003 OPTICAL TACHOMETER CALIBRATION ADAPTER OPERATION MANUAL Null Function (Current Measurement) The null function allows each current range to be nulled independently. To set the null, the terminals should be OPEN CIRCUIT. If auto range a null. is selected, the virtual front panel will step through each range and perform Set Infinity Function (Resistance Measurement) The set infinity function allows The infinity point of each range to be set independently.
