3.8 AC Current Probe MN193 Probe
When installing probes, face the arrow on the probe in the direction of
the load.
The 5A range of the MN193 is designed to work with secondary current transform-
ers. Best accuracy is available when entering the transformer ratio (e.g. 1000/5A).
When used to measure 5A direct, the resolution will be limited to 0.1A max.
Nominal Range: 5A and 100A
Measurement Range:
5A: 0.005A to 6A
100A: 0.1A to 120A
Currents < (Primary x 5) ÷ (Secondary x 1000) or < 250mA on the 5A range
and <0.2A on the 100A range will be displayed as zero with this probe. Power
calculations will also be zeroed when the current is zeroed.
