Power Sources - GE Druck TRX-II User Manual

POWER SOURCES

Power from internal batteries
Internal power is obtained from 4x 1.5 V Alkaline batteries or four
1.2V, rechargeable batteries, Model R14, Baby or C size.
Note: Not applicable for Model TRX-II IS.
Installation of the batteries
Switch the calibrator off before installing new batteries.
Note: Not applicable for Model TRX-II IS.
Release both mounting screws retaining the battery compartment
cover. Remove the old batteries and check that the contact plates
are clean. Place the new batteries in position observing polarity as
indicated.
Use of Alkaline batteries (supplied as standard)
The calibrator is supplied with one set of 4 Alkaline batteries. Check
that the Battery Selector Switch is in the "Alkaline" position before
replacing the batteries. Battery switch position will be confirmed on
the screen during start-up of the calibrator. Replace batteries when
the screen shows the battery symbol.
• Be sure that batteries are inserted so that they are placed correctly
with respect to the (+) and (-) indications in the battery
compartment. If the batteries are not inserted correctly, they may
leak and damage the calibrator.
• Do not mix old and new batteries, or batteries of different types
(such as carbon and alkaline.)
• If the calibrator is not to be used for a long period of time, take out
the batteries.
• Remove and dispose of worn-out batteries.
• Never attempt to recharge or short-circuit the batteries.
Changing from Alkaline to Rechargeable batteries
Remove the Alkaline batteries. Slide the battery type switch to the
"Ni-Cd" position.
Install 4 rechargeable batteries (purchased locally). Battery switch
position will be confirmed on the screen during start-up of the
calibrator. Recharge batteries when the screen shows the battery
symbol.
Never place Alkaline or other non-rechargeable batteries after
Recharging batteries
Use the Line Adaptor/Charger #13603 only; other equipment may
cause damage to the calibrator. Check the indicated Line Voltage
and turn the charger switch on. Connect the appropriate Adaptor/
Charger plugs to the line and to the calibrator.
As the adaptor and charger functions are fully independent from each
other, the calibrator can be used while charging.
Recharging time from fully discharged to fully charged is 14 hours.
You may charge for periods longer than 14 hours. Note that at lower
ambient temperatures, the capacity of Ni-Cd batteries is significantly
