Model 3450 5–3
Place the gauge base in a secure location where liquid and dirt
cannot enter the gauge (which could damage the baseboard
assembly in the bottom of the gauge). The gauge NiCad batteries
can be charged with the control unit detached.
The control unit can now be operated independently of the gauge.
The control unit is fully functional except that it cannot take a
measurement, and cannot read the temperature sensor or perform
diagnostics on the baseboard assembly.
The 9-pin serial connector on the side of the control unit can be used
to transfer data from the control unit in the same way that the serial
connector on the rear of the gauge is used. Take care not to touch or
damage the baseboard connector on the side of the control unit as
damage to the electronics could result. Also, the control unit should
only be removed when the gauge is inside (not outdoors) so the
control unit does not become wet or dirty while separated from the
gauge.
Before returning the control unit to the gauge base, turn off the
control unit and disconnect the charger from the gauge.
To return the control unit to the gauge, reattach the baseboard
connector to the control unit, taking care to align the connector
properly. When properly aligned, the connectors should slide
together easily without forcing. Push the connector in until the
latches on each side click into the locked position. On gauges
equipped with a shielded ribbon cable, secure the cable using the
flat metal bracket.
Ensure that the shielding of the cable is
gripped securely beneath the metal bracket. Replace the two
Phillips screws and tighten.
CAUTION
Turn the gauge off before reconnecting the control unit.
Unexpected operation or board failure may result if the
control unit is connected while turned on.
