VOLTMETER AND RANGE SWITCH
The KILOVOLT METER and associated range switch allows for more accurate output voltage readings. 1-%
precision resistors minimize the need for re-calibration due to aging shift. See Voltmeter Re-calibration in
Section3 for detailson calibration.
CURRENT METER
The CURRENT METER is for accurate secondary load current readings. The range multiplier switch (X1,
X10,X100) allows readingsto betaken aslow as.1mA (5divisions) andup to 100mA.
LOAD RETURN CONNECTOR
The LOAD RETURN connector is for the low side of the test load. It connects to the shielded return lead for
moreaccurate load currentreadings.
RETURN MODE
The RETURN MODE switch allows for accurate secondary load current readings. In the GUARD position, all
ground currents are shunted around the meter. The load must be isolated from ground to use in the GUARD
position. In the GROUND position, the return point is grounded and all currents (load and ground losses) are
metered.
BURN(OPTIONAL)
The BURN toggle is provided for tests when the load has faulted and the insulation must be further scored to
find the problem. The BURN feature will limit current on the output below the overload value and allow for
thoroughmarking ofthefaultarea.
