Calibrator
Introduction
The Beta MasterCAL Calibrator (hereafter referred
to as the calibrator) is a battery-powered, hand-held
instrument that measures and sources electrical and
physical parameters, and provides basic HART
communicator functions when used with HART-
capable transmitters. Refer to the
MasterCAL
HART Mode Users Guide for instructions on how
to use the HART communication feature.
The calibrator lets you troubleshoot, calibrate, verify,
and document your work on process instruments.
Calibrator Specifications are at the back of the
manual.
A summary of the measuring and sourcing functions
provided by the calibrator is shown in Table 1. In
addition to these functions, the calibrator has the
following features:
•General features:
An analog display to make it easy to read
measurements when the input is unstable.
A setup option that lets you set the display to
English, French, German, Italian, or Spanish.
A thermocouple (TC) input/output jack and
internal isothermal block with automatic
reference-junction temperature compensation.
Or, you can manually enter an external
temperature reference.
The ability to store results for later review.

MasterCAL

The ability to automatically log up to 8,000 data
points.
A serial computer interface for
uploading/downloading tasks, lists, and results.
Automatic calibration procedures for
transmitters and limit switches using split screen
MEASURE/SOURCE mode.
Transmitter mode in which the calibrator can be
configured to emulate the functions of a process
instrument.
Built-in calculator with square-root function, and
accessible registers containing measure and
source values.
An optional bar code wand for entering
alphanumeric characters.
•Measuring features:
Damping (smoothing of the last several
readings), with display indicator of damped
status.
Display of measurements in engineering units,
percent of scale, square-law inputs, or custom
units.
The ability to capture and display minimum and
maximum measured levels.
•Sourcing features:
The ability to set source values to engineering
units, percent of scale, square-law outputs, or
custom units.
Manual and automatic stepping, and an output
ramp feature for testing limit switches. Trip
detect is either a 1 V change or a continuity
status change (Open or Short) from one ramp
increment to the next.

Safety Information (cont)
A Warning identifies conditions and actions that pose
hazards to the user; a Caution identifies conditions
and actions that may damage the calibrator or the
equipment under test.
WWarning
To avoid electric shock or personal
injury, adhere to the following practices:
•Do not use the calibrator if it is damaged.
Before you use the calibrator, inspect the
insulating cover. Look for cracks or missing
plastic. Pay particular attention to the
insulation surrounding the connectors.
•Disconnect the power and discharge all high-
voltage capacitors in the equipment under
test before testing resistance or continuity.
•Inspect the test leads for damaged insulation
or exposed metal. Check test lead continuity.
Replace damaged test leads before using the
calibrator.
•Do not use the calibrator if it operates
abnormally. Protection may be impaired.
When in doubt, have the calibrator serviced.
•Select the proper function and range for your
measurement.
•Use caution when working above 30 V ac
rms, 42 V ac pk, or 60 V dc. Such voltages
pose a shock hazard.
•When using the probes, keep your fingers
away from the probe contacts. Keep your
fingers behind the finger guards on the
probes.
•Connect the common test lead before you
connect the live test lead. When you
disconnect test leads, disconnect the live
test lead first.
•Replace the battery as soon as there is a low
battery indication on the display. The
possibility of false readings can lead to
electric shock and personal injury.

Safety Information (cont)
WWarning (cont)
•Do not apply more than the rated voltage, as
marked on the calibrator, between the
terminals, or between any terminal and earth
ground.
•When using probes, keep your fingers
behind the finger guards.
•Do not use the calibrator with any part of the
case or cover removed.
•Do not operate the calibrator around
explosive gas, vapor, or dust.
•When using a pressure module, make sure
the process pressure line is shut off and
depressurized before you connect it to or
disconnect it from the pressure module.
•Disconnect test leads before changing to
another measure or source function.
•When servicing the calibrator, use only
specified replacement parts.
•Do not use any battery eliminator other than
the Fluke model BE9005 Battery Eliminator.
Caution
To avoid possible damage to the
calibrator or the equipment under test,
follow these guidelines:
•Disconnect circuit power and discharge all
high-voltage capacitors before testing
resistance, continuity, diodes, or
capacitance.
•Use the proper terminals, function, and range
for your measurements.

Getting Started Exercise
The following is a brief getting started exercise that
will make it easier to understand the instructions in
the rest of the manual.
1. When you first unpack the calibrator, you will
need to charge the battery. See Figure 9 and
charge the battery for 2 hours.
2. Reinstall the battery in the calibrator.
3. Connect the calibrator’s voltage output to its
voltage input as follows: connect leftmost pair of
jacks (V ΩRTD SOURCE) to the right most pair
of jacks (V MEAS). (See Figure 3.)
4. Press oto turn on the calibrator. Press uand
dto adjust the display contrast for the best
looking display. The calibrator powers up in the
dc voltage measurement function, and is taking
readings on the V MEAS pair of input jacks.
5. Press sto switch to the SOURCE screen.
The calibrator is still measuring dc voltage, and
you can see the active measurements at the top
of the display.
6. Press vto select dc voltage sourcing.
Press 5 on the keypad and eto begin
sourcing 5.0000 V dc.
7. Now press Mto go to the split-screen,
simultaneous MEASURE/SOURCE mode. The
calibrator is simultaneously sourcing dc volts
and measuring dc volts. You can see the
measurement readings in the top window, and
the active source value in the bottom window as
shown in Figure 4.
