1.3.3 If the current exceeds the limits in the table above, then isolate the source of the
excess consumption by removing components one at a time. CAUTION: turn off the
power supply before removing sensors or lamps. The pump current can be checked by
stalling the pump and observing the change in current.
1.3.4 Replace the component found to consume excess current. If the cause of the excess
current consumption cannot be isolated, then the unit must be returned to the factory or
an authorized service center.
1.4 Battery voltage Measurement Circuit
1.4.1 Follow the steps in 1.3.1 (the current meter is not necessary).
1.4.2 Turn on the power supply. Turn on the MultiRAE. Press [MODE] to get to the
battery voltage display. The display should read 4.8V
1.4.3 Increase the voltage to 6V. The display should read 6V.
1.4.4 Slowly decrease the power supply voltage. At 4.4V the display should begin
flashing “Bat”. At 4.2V the unit should turn off.
1.4.5 If any of these tests fail, the unit should be returned to the factory for repairs.
1.5 Battery Condition Tests (use for NiCd battery packs only)
1.5.1 Charge the batteries for 8 hours, either in the MultiRAE or in an external charger
(P/N 008-3027).
1.5.2 Measure the voltage across pins 1 and 3 of the battery connector (test procedure
1.1.4). If the voltage is 4.2V, then the battery is good and no further testing is needed. If the voltage
is
