Ceramic ps are fragile and used for direct contact with ESD sen-
sive devices and assemblies. Metal ps are robust and used to
measure equipment, xtures, tools and other non-ESD sensive
elements.
C. Connect the CVM-780 to a previously tested ground to provide a
dened reference for accurate measurements
D. CVM-780 intended measurement range is 0 - ±525 volts in
one volt increments. All measurements are immediately
shown in the 3 digit LED display. Polarity switching during
measurements is automac
E. The round brass front panel
ground plate is used as a
zero reference for the
instrument. Between
measurements the probe
p (ceramic or metal pin) is placed in contact with the ground
plate to conrm the probe p’s zero voltage as displayed on the
panel LED. Instrument zero is adjusted using the manual adjust-
ment provided below the LED display.
F. An analog output mini-jack receptacle is provided for monitoring or recording CVM-780 measure-
ments. The analog output jack provides an output of 0.1 millivolt for each 1.0 volt measured by
the CVM-780. The output is independent of the meter indicaon to maximize response me. The
output is compable with the Prostat® PGA-710 or PGA-710B Autoanalysis System™.
G. A universal AC/DC baery charger is provided for charging the AA sized Metal Hydride recharge-
able baeries. Baery life is approximately 3.5 hours. Fully charged baeries should provide a full
day of measurements if the unit is turned OFF when not in use.
