To change any setting, use the Mode button to cycle through the choices
(0 or 1 for Options 0, 3 and 4; 0, 1, 2 or 3 for Options 1 and 2). When the setting
you want appears as the right digit on the display, press the button to save
it. Each time you save a setting, the display advances to the next Option. To
leave a setting unchanged, press the button to advance to the next Option.
Once a setting has been chosen for Option 4, the meter will automatically exit
Setup mode and enter Measurement mode. You cannot access the Options out
of sequence. For example, if you have disabled the beeper (by pressing the
button with “1 = 3” on the display), you cannot re-enable the beeper without
powering off the meter and re-entering Setup mode.
The one exception to this rule is the setting of the display backlight. You can
turn the backlight on or off by pressing the Mode button and holding it for at
least three seconds.
CHECKING CALIBRATION
Option 4 gives you two choices for checking the calibration of the meter.
Choosing Setting 0 lets you check the calibration manually. Setting 1
automatically checks the calibration of the meter each time it is powered on.
To check the meter’s calibration manually, press the and Mode buttons
at the same time while operating in %WME measurement mode. This will
cause the text “CAL” to flash twice on the display and the beeper to sound
twice. Remove the protective cap from the top of the meter, taking care not to
stab yourself with the two sharp test pins beneath it. Then flip the cap over and
place the two holes in its top over the meter’s two test pins. The display should
read 40% ±3%.
If the calibration check produces a reading higher than 43% or lower than
37%, and the meter is still under warranty, call General's Customer Service
Department at 212-431-6100 to arrange to return the meter for service or
replacement.
