2. Bath temperature calibrations and offsets
The previous Section H dealt with the setting of individual temperature
correction bins for temperature calibrations at any given set temperature.
When the user enters a 2 in the MAIN MENU, the following display is
shown. It is possible to clear (or zero) ALL bin calibration data or enter
the GENERAL BATH OFFSET menu.
Whenever a 1 is entered in the BATH TEMP OFFSET menu, the follow-
ing screen is shown. This command will clear ALL of the temperature
correction "bins" for degrees Celsius AND Fahrenheit which may have
previously been set. This command is usually used prior to adjustment of
the "general bath offset". This command may also be used if significant
differences become apparent between the user supplied reference tem-
perature and the displayed temperature of the bath or if CAL TEMP
entries were made when the bath was not stable. Once this "clear"
command is issued, new calibration entries may be made in the CAL
TEMP menu.
Whenever a 2 is entered in the BATH TEMP OFFSET menu, the follow-
ing screen is shown. The setting of the BATH GENERAL OFFSET
mathematically compensates all temperature readings displayed as
"Actual Temperature". This function is normally performed at the factory
prior to shipment of the instrument and is accomplished at a temperature
near the midpoint of operation of the TE-3000. This function is pass-
word-protected so the user must contact CANNON
pany if access to this capability is required.
Once the correct password is entered, the user will be presented with the
following display. The current "general bath offset" is displayed as a
delta in degrees and two choices are permissible.
