during the testing process. If this occurs, simply
dab the pen probe tip on a dry paper towel a
few times and this should remedy the problem.
ALWAYS REINSTALL THE CAP WHEN NOT
IN USE. Because the chemical properties of
the pen probe will continually change over time
and normal use as the solution is depleted, it is
recommended that the pen probe calibration be
checked periodically throughout ongoing use.
Please note that sometimes when the pen probe
is plugged in the REPLACE PROBE light will
illuminate briefly. This should be ignored. If when
the pen probe is first plugged in the REPLACE
PROBE light remains illuminated, this is a
normal occurrence and will be remedied by
simply calibrating the AGT1 as described in
#4 below. If calibration does not remedy this,
it is a sign of a defective or spent pen probe. If
it is a defective pen probe, be aware that the
REPLACE PROBE light will not go out until a
good pen probe is connected to the AGT1 and
it is then recalibrated.
4. BEFORE USING THE AGT1 AND EACH TIME
IT IS TURNED ON, IT MUST BE CALIBRATED.
To calibrate the AGT1 to ensure its accuracy, you
must first obtain a piece of yellow 14K plumb
gold for use as its calibration standard reference
piece. (An approved GemOro calibration standard
reference piece of plumb 14K yellow gold is
available separately as an optional accessory Item
#2002.) FOR CALIBRATION ONLY USE YELLOW
GOLD THAT IS PRECISELY 14K. Be aware that
not all gold marked as 14K is actually .583 - .585
