Using the Input Terminals

All functions except current use the *and

COM inputs. Current functions use the inputs shown

below:

•

I or K function: Use A and COM inputs from 400

mA to 20 A. Use mA/µA and COM for inputs ≤ 400

mA.

•

= or x function: Use mA/µA and COM for inputs ≤

5000.0 µA.

If a test lead is plugged into the mA/µA or A terminal, but

the rotary switch is not correctly set to one of the current

measuring positions, the Input Alert™ beeper warns you

by making a chirping sound and the primary display shows

"LEAd5". This warning is intended to stop you from

attempting to measure voltage, continuity, resistance,

capacitance, or diode values when the leads are plugged

into a current terminal.

Figure 2-5 shows the input terminals.
