General Tools and Instruments DAMP68 v.2 - Manuel (Page 7)

MEASURING DC VOLTAGE
Ꮨƽ Warning
Do not measure voltage higher than 600V. Doing
so may damage the meter’s internal circuitry. If
the voltage is over 1000 VDC, the beeper will
sound continuously, indicating an over-range
measurement.
(1) Set the function switch to the position.
(2) Plug the black and red test leads into the
– and + input terminals, respectively.
(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 test leads are reversed, a minus sign will
appear to the left of the displayed value.

press the SHIFT button to select DC current
measurement. Before measuring DC current,
press the
ZERO button to clear (offset) the
last reading from the display.
(2) Squeezing the clamp jaw release to open the
jaw, place it around the conductor whose
current you wish to measure. Be sure to
enclose only one conductor (see figure below).
Enclosing both conductors of a pair will
produce a reading of 0.
Note:
General’s ACL10 line splitter makes it possible
to safely attach the DAMP60 or DAMP68 to
a line cord carrying up to 15A AC without
separating its conductors, thereby damaging
the cord. For more information or to order, visit
www.generaltools.com and enter “ACL10” in
the SEARCH box.
(3) Read the measured value from the display. In
the case of the DAMP68, the displayed value
is a True RMS reading.
Notes:
Clamp the jaw around one
conductor only.
Close the jaw completely.
Center the wire in the jaw
for highest accuracy.
