3.
Set the following conditions:
a
Set to TEST position.
b.
Set to desired MAXIMUM TEST CURRENT.
c.
Set to desired DATA OUTPUT.
4.
Connect "V1" voltage leads input to H1 and H2 terminals of test
transformer. See Figure 3.
5.
Connect "V2’ voltage leads input to X1 and X2 terminals of test
transformer. See Figure 3.
Connect current leads (I) to test specimen winding. See Figure 3. Add the
Jumper Cable from H2 to X1. This will allow current to flow from the
primary winding to the secondary winding.
Voltage leads should
always be placed inside (between) current leads and the
transformer.
See Figure 3.
NOTE:
Always try and keep the polarization of the transformer the same for
improved transformer charge time. If the positive lead for the current is
connected to the positive terminal of the primary winding, follow this
procedure by driving the current from the primary winding H2 jumpered
to the positive terminal of the secondary winding X1.
6.
Turn power Switch "ON" (-). Press
button to initiate current flow.
7.
The top smaller display indicates current output and the Ohm1 display
indicates resistance of primary winding and Ohm 2 display indicates the
resistance of the secondary winding specimen.
8.
When measurement is complete, press
to end the measurement
and discharge current. Discharge is complete when discharge indicator is
OFF(0).
