MasterCAL 990 Multifunction Calibrator
The MasterCAL 990 Multifunction
Calibrator is a precision, multi-function documenting
calibrator
that will calibrate virtually any process instrument you have
thermocouples, RTDs, Ohms, Voltage,
current, pressure, and frequency. A host of convenience
features, including source ramp functions,
loop power, variable density data logging with a week’s worth of
calibration results storage, compatibility
with many third-party calibration documentation software
programs, and a built-in HART configuration
and communicator, make the MasterCAL 990 an indispensable tool.

Source Simulation
The MasterCAL 990 multifunction calibrator will
source/simulate thermocouple, RTD,
Ohms, DC Voltage and current and frequency.
Auto-step and ramp functions are provided on all outputs
and ranges.
Measurement Read
The Multifunction Calibrator will measure/read
thermocouple, RTD, Ohms, DC and AC
Voltage, DC current, pressure, and frequency.
Measuring pressure requires the use of the Beta Pressure
Module Adapter (Model BPPA100)
with any of Beta’s Pressure Modules (please refer to the
separate Pressure Module data sheet
for ranges and accuracies).
Simultaneous Measure Source
Using a split-screen display mode, the MasterCAL 990 will
simultaneously
measure and source various process variables.
These variables depend on whether loop power is enabled
or disabled.
Transmitter Mode
The MasterCAL 990 multifunction calibrator can be inserted
in a 4-20 mA process loop
to simulate a 2-wire transmitter.
The MasterCAL 990 provides the loop excitation and
modulates the loop current, simulating the 2-wire
transmitter.
Switch Test Mode
Process limit switches can be tested for both upper and
lower trip limits and deadband.
Using a split-screen measure/source mode, the MasterCAL 990
calibrator accepts a normal process
variable measurement associated with the limit switch, and
the switch contacts.
The 990 will automatically monitor and record the
measurement as the switch is activated and then
deactivated.
A graphical plot of deadband is displayed, making switch
test quick and accurate.
Built-In Calculator Functions
The MasterCAL 990 calibrator features a built-in
calculator
with square-root function, with accessible registers
containing measure and source values.
Barcode Entry Options
The MasterCAL 990 Multifunction Calibrator will accept input
from an optional barcode
wand for rapid entry of instrument serial numbers.
