I have an aemc simple logger 11 model l562.My question is on how to set this logger as to which scale multiplier setting to use.
input one is 0-1v scale choices are 10mv/ma,1mv/ma,100mv/a
1mv/a or 0.33mv/a this input is for a clamp amp probe

input two is 0-600vac the scale multiplier settings are 1,100 or 10
the manual that came with this unit does not give much info on setting up the scales multipliers.
I can make this unit work but would like a better understanding on how best set this logger up.
I use it to find problems in homes and business eg when did the voltage drop out or current rise etc.
can anyone recondmend a book on this topic?

I would use the 600v scale set up 1:1 for 120/240.

You can also hook up the clamp to track line in current so you can see if the dip was caused by your load spiking or was a utility problem.

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_ as follows:

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! frown
