Operation and Service Manual
Set Date and Time
The Set Date and Time screen menu option is used to setup the date and time that is used on the test report. The time and date are
internally stored and automatically updated when the unit is powered up.
To enter time, use the encoder knob to select the hours and minutes. Note: the hours is setup using a 24 hour clock format, where
1PM is entered as 13:00 etc. When the value is correct, push the encoder knob to move to the next field of the time and then to the
date field. The date field is setup using a MMDDYYYY format. After the last field of the date is entered, the next encoder push will exit
this menu and return to the Main Menu. Note: the time and date are shown at the bottom of the Main Menu.
Check Calibration
This menu option performs the calibration check of a GENIUS 2 Thermometer, and if required, automatically recalibrates the
thermometer using a series of step-by-step screens. Before entering this menu option, make sure that the required equipment listed
in Section IV is available. This includes a cassette with unused (new) probe covers.
Step 1:
Warm up of infrared blackbody targets. This screen is displayed while the targets are checked for proper temperature. Both the Low
Target and the High Target are checked, and when they are at the correct temperature, the screen will change to “OK” for each target.
There is a prompt to press the encoder knob to continue to the next screen. If either target cannot reach the correct temperature,
an Error message screen will be displayed. If this happens, check to be sure the GENIUS 2 Checker/Calibrator is within the correct
ambient (room) temperature range, and has been given at least 15 minutes of warm up time since power was switched on.
Step 2:
Inspect the GENIUS 2 Thermometer that will be tested. Ensure that the thermometer lens is not scratched and is free from ear
wax and/or other contaminants. If the thermometer lens is “dirty”, clean the lens according to the instructions in the GENIUS 2
Thermometer operating manual. Once the thermometer lens is clean, connect the GENIUS 2 Thermometer to the Checker/Calibrator
by plugging the round end of the thermometer interface cable into the round connector socket on the GENIUS 2 Checker/Calibrator
front panel (refer to Figure 3). Open the battery door of the thermometer by using a small Phillips screwdriver. Remove the batteries
and set aside. Connect the other end of the thermometer probe cable into the battery compartment, making sure the connector
“snaps” into place securely. Refer to Figure 2 in Section V.
Note:
A new probe cover must be used prior to every target insertion. Finger oils on previously used probe covers or re-used
probe covers that have been heated by GENIUS 2 Checker/Calibrator target can cause erroneous readings which may
result in a failed calibration check or recalibration. Therefore, it is extremely important that a new probe cover is used
each time.
Step 3:
Press the encoder knob to continue, then install a new GENIUS 2 probe cover onto the GENIUS 2 Thermometer. Make sure to use a
cover that is held in the cassette. Once the cover is on the thermometer, do not point the probe tip at any object, including hands,
fingers or LCD display, as this will cause an inaccurate temperature reading. Inspect the probe cover to make sure it is fully seated (no
space between the cover and the tip base) and no holes, tears, or wrinkles are present in the plastic film. When the cover is on, insert
the probe tip into the Low temperature target, which will have a blinking LED indicator next to it. Make sure that the probe tip is fully
inserted into the target well. Refer to Figure 3 for proper insertion. In order to avoid a time-out error, insert the covered probe tip into
the target within 60 seconds from the time the encoder knob is pressed.
