This Device _APPEARS AS_
a Power Monitor, for logging a Single Phase Circuit over a given Time Period.
Input #1 would be the Current Probe Input, via a Clamp-On type Ammeter (Current Transformer type Current Probe).
Connect a compatible CT to the "CH-1" Input on the Meter.
Set the Parameters for CH-1, per the specifications of the Current Probe used.
Clamp the CT around ONE Conductor on the Circuit to be Monitored.
Input #2 would be the Voltage Probe Input.
This may be via:
1: Voltage Probe Leads of the Current Probe,
2: a Pair of Alligator Clipped Voltage Leads, connected to the Two Wires of the Monitored Circuit, at a Termination Point (so as to measure the Circuit's Voltage).
The Multiplier settings for CH-2 _MIGHT BE_
A: Using the Current/Voltage Probe: 100:1,
B: Using Alligator Clip Leads: 1:1
These figures are not device specific, so best to verify prior to actual use.
Do a Google Search for your Model Number. This might yield more information than what is found in the Document you have now.
Good luck... sorry I could not give you actual answers!
