• NOTE 3: Insert an external shunt/ammeter in series with any of the
battery leads (Use the Single Cell adaptor to facilitate the
connection or simply use the CAL-100 which is a calibrator
designed specifically to test and certify Charger-Analyzer Battery
Charger-Analyzers.
• NOTE 4: The charge output current wave is in the form of short
pulses (at twice the line frequency). The use of clamp-on meters
and moving magnet meters will yield erroneous readings. Verify in
discharge (pure DC) if better meters are not available.
9.2.2. VOLTMETER.
9.2.2.1. ZERO: No zero adjustments.
9.2.2.2. SCALE:
• This meter has a full scale of 1.999 volts, but an attenuator on the
board converts it to a full scale of 1.999, 19.99 or 199.9 volts, as
selected by the DPM selector switch.
• Verify and calibrate using a voltage source (Power Supply or
CAL-100, as a battery voltage simulator) between 10 and 20 volts
in the "EXTERNAL 20V" position.
• Adjust R17 for a reading within " 0.01V of the reference voltmeter.
• NOTE: individual scales cannot be adjusted.
