Introduction
The MCX-II calibrator
The Multi-Calibrator model MCX-II has
8
been designed for testing and
calibration of process instrumentation
and portable test equipment. The unit
provides data to comply with the
ISO9000 requirements for calibration.
The MCX-II can be used to measure
and output analog and digital signals
often used in an industrial
environment.
Also it can be used to simulate a
wide variety of temperature sensors.
Measurement and output/simulation
functions can be operated and read
simultaneously.
Pressure Measurements and Calibrations
A plug-in Pressure Module model
MCX-PM is optionally available for
pressure measurements and
calibration.
K0320 Issue No. 1
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 MCXII is supported by Intecal software. The
software package and Memory Cards
are optionally available from your local
GE Sales Office or Distributor.

Screens to work with
The MCX-II has four types of screen
display to work with:
• Menu Selection Screen
Offers selection of choices. Move
cursor with arrow keys to your choice.
• Set up Screen
Move cursor with arrow keys to fill in
the blanks.
• Working Screen
Displays readings of measured and
generated values. Output or simulated
temperatures are set with the
numerical key-pad or can be ramped up
and down in different ways.

NOTE:
After switching the calibrator
on, the screen will show:
• Serial Serial Number
• Firmware Firmware version
• Hart Hart Firmware
version
• Battery voltage/switch position
• Days left to next calibration

Power Sources
Power from internal batteries
Internal power is obtained from
6 x 1.5 V Alkaline batteries or 6 x 1.2 V
Rechargeable batteries, Model R14, Baby
or C size.
• Installation of the batteries
Switch the calibrator off before you
install new batteries. Release both
mounting screws of the battery
compartment cover. Open the
compartment and place the new
batteries in position as indicated
in the compartment. Check for clean
poles and contact plates before you
replace the batteries.
• Use of Alkaline batteries
(supplied as standard)
The calibrator is supplied with one set
of 6x 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 blinking 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
26
Remove the Alkaline batteries.
Remove the switch protector sticker
and slide the switch to the "Ni-Cd"
position.
Place a new protector sticker to save
the new switch position. Install 6
rechargeable batteries (purchased
locally). Battery switch position will be
confirmed on the screen during startup of the calibrator. Recharge
batteries when the screen shows the
blinking battery symbol.
CAUTION:
Do not fit alkaline or other nonrechargeable batteries after you
have changed the switch position to
"Ni-Cd".
Recharging
Use the Line Adaptor/Charger #13603
only; other equipment may cause
damage to the calibrator. Check the
indicated line volt switch in the
CHARGE position. Connect the
appropriate Adaptor/Charger plugs to
the line and to the calibrator. The
amber led CHG at the calibrator power
panel will now be on. As adaptor and
charger functions are fully
independent from each other, the
calibrator can be used while charging.
Recharging time from complete
discharge to fully charge is 14 hours.
K0320 Issue No. 1
28
Power Sources
You may charge for periods longer
than 14 hours. Note that at lower
ambient temperatures the capacity of
Ni-Cd batteries is significantly lower. If
the batteries do not reach their normal
capacity after a 14 hours charging
period, cycle complete discharging
and charging for at least 2 times. If
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
general available 1.8 Ah cells.
Operating from 115 V or 230V line voltage
(50 or 60 Hz)
Use the Line Adaptor/Charger #13603
only; other equipment may cause
damage the calibrator. Check the
indicated line voltage. Connect the
appropriate Line Adaptor/Charger
plugs to the line and to the calibrator.
The green led EXT at the calibrator will
now be on.
