INTRODUCTION
The TRX-II Calibrator
The Multi-Calibrator model TRX-II has been designed for testing and
calibration of process instrumentation and portable test equipment.
The unit provides data to comply with the ISO 9000 requirements for
calibration. The TRX-II can be used to measure and source
analogue and digital signals often used in an industrial environment.
It can also be used to simulate a wide variety of temperature sensors.
Measurement and source/simulation functions can be operated and
read simultaneously.
Model TRX-II IS marked with label “Ex” has been built in accordance
with European Norm II 2 (1) G EEx ia IIC T5 and may be used in IEC
defined zones 0,1 and 2. for special precautions for use deviations to
the standard unit see the chapter “SUPPLEMENT FOR
INTRINSICALLY SAFE CALIBRATOR TRX-II iS”.
Pressure Measurements and Calibrations
A range of pressure sensors is optionally available for pressure
measurements and calibration.
Automatic Calibration
To automate calibration routines and to store calibration data the unit
has been provided with a memory card slot. For the same purpose
the unit has a RS232 cable connector to interface directly with a
Personal Computer. To perform automatic calibration, in the field or
in the workshop, the TRX-II is supported by a Druck Calibration
Management software. The software package and Memory Cards
are optionally available from your local Druck Sales Office or
Distributor.

EN-6 K319 Issue 2
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.
IMPORTANT:
• 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.
WARNING:
Never place Alkaline or other non-rechargeable batteries after
setting the switch position to "Ni-Cd".
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

K319 Issue 2 EN-7
English
lowered. If the batteries do not reach their normal capacity after a 14
hour charging period, cycle complete discharging and charging at
least twice. If the batteries remain weak they should be replaced. No
particular brand of Ni-Cd is recommended although cells rated at 2.0
Ah have preference over the more generally available 1.8 Ah cells.
Operating from 115 V or 230 V line voltage (50 or 60 Hz)
Use the Line Adaptor/Charger #13603 only. Other equipment may
cause damage to the calibrator. Check the indicated line voltage.
Connect the appropriate Line Adaptor/Charger plugs to the line and
to the calibrator.
Note: Not applicable for Model TRX-II iS.
