2.3.7. Adjusting the Voltmeter Accuracy
The AT10.1 voltmeter is adjusted at the factory to display the actual dc
output voltage within ±0.25%. If you replace any component that affects
meter accuracy, such as the Main Control PC Board (A1) or
R4 , you
should readjust the meter. This adjustment procedure is different from all
others, because the meter reading remains constant, while the output
voltage of the AT10.1 changes. Do this adjustment with a fully charged
battery and with no load connected.
•
Enter Edit Mode to adjust the AT10.1 float voltage to the desired
value. See Section 2.3.2 on page 31 for adjusting the voltage.
•
After entering the float voltage, exit Edit Mode by pressing the
EDIT/ENTER
key four (4) times until the AT10.1 returns to
normal operation. If you do not press any front panel key for 25
seconds,
Edit Mode ends automatically, and any change made to
the last setting is not saved.
•
After successfully exiting Edit Mode , you may adjust the
voltmeter accuracy. Press and hold the
UP
key, then press the
EQLZ MTHD
key.
•
The
DC VOLTS METER MODE
indicator will light, and the
front panel display flashes the dc output voltage reading.
•
Measure the AT10.1 dc output voltage using a meter accurate to
±0.25% or better.
•
While watching the meter connected to the AT10.1 output (not the
front instrument panel display), press the
UP
or
DOWN
key until
the actual (meter) output voltage matches the float setting on the
front panel display.
NOTICE
Allow 1-2 seconds for the output voltage to stabilize
each time you press the
UP
or
DOWN
key.
Each time you press
UP
or
DOWN
, you change the AT10.1 output
voltage by a small amount. Continue to press
UP
or
DOWN
until
the actual (measured) output voltage agrees with the front panel
display reading within ±0.25%.
•
When you are finished adjusting the output voltage, the AT10.1
waits 5 seconds before the front panel display automatically returns
to normal operation.
