2-7. Performance
Verification
Verification of the performance of the Model 2300 may be performed at any time, and is especially
recommended following receipt of the unit or following transportation. Verification may be achieved
with two levels: verified as operational; verified as operational and within specifications. The
procedures for both are given below.
2-7-1. Verification of Operation
If the 2300 fails any of the tests below, employ normal troubleshooting procedures or consult the factory
for advice.
1) Ensure that the POWER switch (lower left hand corner of the front panel) of the 2300 is in the OFF
position, i.e. no yellow dot showing.
2) Ensure that the rear panel switch is set to the correct local line voltage and apply AC power to the
2300. Make no connections to the shunt input terminals under the flip lid.
3) Press the 2300 POWER switch to the ON position (yellow dot showing). The LED's on the front
panel should illuminate in the 600V, 100A and φA positions, and the displays should indicate near
zero. Wandering displays or continuous illumination of any overload indicator signifies
that a problem may exist.
