Setup to Measure Current

The procedure for setting up your SmartReader Plus 3 is as follows:
1. Connect one or more current probes, specified above, to the current channel inputs on
your SmartReader Plus 3. Make sure to observe polarity when making connections.
Connect the current probe's red (+) wire to the channel's "+ Red" input. Connect the
current probe's black wire to the channel's "- Black" input.
2. Adjust the range setting on the current probe(s) to suit your application. A good way to
verify a conductor's maximum range is to check the circuit breaker or fuse rating. Set the
range on your current probe to suit. Since the probes do not give predictable readings
below 10% in any range, always choose the lowest range possible to encompass the full
range of data you want to record.
3. Make sure to enable each channel you want to use. If you are not using a channel,
disable it in order to save memory.
