ORDERING INFORMATION

Specify code number and variables (e.g. LSMT2-

2150A1-M). Use Ordering Information Sheet (No.

ESU-1954-2).

The unit is configured at the factory according to the

user's specifications, however, measuring items can be

freely selected and assigned to up to 10 output chan-

nels via the front panel control switches.

The measuring items are listed below:

A = Line current

V = Line voltage

W = Watt, active power

PF = Power factor

Hz = Frequency
