Note:
General’s FX3000 Flex Clamp Adapter makes it possible
to measure the current carried by a thick or hard-to
reach conductor, a bundle of conductors, or a busbar
carrying up to 3000A. The accessory uses induction to
convert current readings to millivolt values that can be
displayed by the DMM52FSG or DMM53FSG. For more
information or to order, visit www.generaltools.com and
enter “FX3000” in the SEARCH box.
MEASURING AC OR DC VOLTAGE
••
Warning
••
Do not measure any AC or DC voltage higher than 600V.
Doing so may damage the meter’s internal circuitry.
(1) Turn the rotary switch to one of the
or
positions, depending on the type and amplitude of
voltage you expect to encounter. If you are unsure
what type to expect, select one of the
positions.
If you are unsure what amplitude to expect, select the
600
position.
(2) Plug the black test lead into the front-panel
COM
jack
and the red test lead into the
(DMM52FSG) or
(DMM53FSG) jack.
(3) Touch the black test lead to the lower-potential point
of the circuit under test, and the red test lead to the
higher-potential point.
(4) Read the measured voltage on the display. If the
readout is
1.
, the voltage level is beyond the currently
selected range. If that is the case, move the rotary
switch to the next-widest position. When measuring
DC voltage, if the test leads are reversed a minus sign
will appear at the left of the readout.
MEASURING RESISTANCE
••
Warning
••
To avoid electrical shock or damage to the meter when
measuring resistance, turn off all power to the circuit and
discharge all high-voltage capacitors.
