3.38 "Tnn/t" – Set Thermistor Type
Enter the channel's (nn) thermistor type (t). This command allows a specific thermistor to be
assigned to each individual channel (generally the external thermistor that is incorporated into
the VW gage). Entering T1/0 sets the external thermistor type of Channel 1 to the standard
3KΩ@25ºC NTC (default). For example, entering T2/1 sets the external thermistor type of
Channel 2 to the high temperature BR55KA822J 8.22KΩ@25ºC NTC thermistor. Entering T3/2
sets the external thermistor type of Channel 3 to the high temperature 103JL1A 10KΩ@25ºC
NTC thermistor.

3.39 "TR" - Display Current Trap Count

The trap counter is a register that keeps track of the number of times that the internal processor
has detected a communications error. This is a useful register to check if communication
problems are suspected.

3.40 "TR0" - Reset Trap Count

Reset the TRap count register to zero.
3.41 "VL" – Display Coin Cell Voltage
The internal 3V lithium coin-cell is used to supply power to the real-time clock circuit. The 3V
lithium coin cell life is rated at 10 years minimum.
*VL
Lithium Cell Voltage = 2.92V
