5. Diagnostic Test
This function should be performed by a train technician and
under InstroTek’s instructions. In this mode the gauge can
check the following components and functions of the gauge:
Battery Voltage, High Voltage, Temperature, Reset Memory
and test the depth sensors.
Battery Voltage
This function measures and displays the total voltage on
the 6 AA NiMH batteries. The maximum measurable
voltage on the battery packs is approximately 9 volts.
The low voltage indicator comes on at 7.0 volts and the
gauge will shut off at 6.6 volts. Based on the condition of
the batteries and the usage, the gauge has a full day of
use from the time of low battery indication to shut off.
Use the car charger adaptor (DC charger) for charging
the batteries in the field.
