Note 1:
DC load meters require an external shunt and potentiometer (not supplied). Use 8
to 10 , 2 watt wire-wound potentiometer. The appropriate shunt should be selected from
accessory section and ordered separately. To select the proper shunt, first obtain the full-
load current rating of your motor from the name plate, manufacturer's specifications of
N.E.C. listing. Multiply that rating by 1.25 and select and order the shunt with an amps rat-
ing as large or slightly larger than the calculated value. Installation and calibration instruc-
tions are included with the meter.
Note 2:
AC load meters must be used with external donut transformers. Complete instruc-
tions for proper selection are included with each AC load meter. Advance assistance in
selecting the appropriate transformer and determining the correct primary/secondary turns
ratio can be obtained from a Simpson technical service representative or authorized service
center.
