LED & Indicator Test
Once a year or whenever displayed numbers seem erroneous, you
should test the LEDs and indicators on the control panel to make
sure they all work. If even one segment of an LED segment does not
work, you could get an incorrect reading in the display.
To test the LEDs and indicators:
1. Set the main power OFF.
2. Set the ROTOR CODE switches to "00" (the setting of all other
switches is irrelevant).
3. Set the main power ON. When you do, watch the control panel
and make sure the displays and indicators light as follows:
• the number 8 should light in each digit space across all of
the displays,
• the minus sign should light in the TEMP display,
• all nine backlit advisory messages should light,
• diagnostic indicators 1 through 12 should light,
• the
∫ω
2
dt
indicator should light.
NOTE
The RCF indicator will not light; to test this indicator, just
press the RCF switch.
If any of the LEDs or indicators are not working, contact a
Thermo
Field Service Engineer to repair it.
