MasterCAL 990 Universal 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.

• Precision multi-function calibrator and HART™ configurator communicator in one hand-held instrument

• Measure/read thermocouple, RTD, Ohms,
  DC and AC Voltage, DC current, pressure,
  and frequency

• Source/simulate thermocouple, RTD, Ohms,
  DC Voltage and current, pressure, and
  frequency

• Simultaneous input and output split-screen
  displays

• Loop power function

• Switch testing functions

• Transmitter mode

• Automated and user-programmable procedures

A large, white backlit LCD provides simultaneous display of input and output.
Menu-driven, “soft” function keys provide rapid setup and measurement. The multilingual interface ensures the MasterCAL 990 is useful in as broad a range of applications and locations as possible.
A high capacity rechargeable battery pack provides extended usage. An optional battery eliminator is available for extended monitoring applications. The MasterCAL 990 is housed in an over-molded urethane case that provides a solid grip and protection against “hard knocks”.

• Engineering units, percent of scale, square law
  inputs, or custom units

• Multi-lingual interface – English, French,
  German, Italian, and Spanish

• 200x240 pixel, bright white, backlit LCD
  display

• Rugged over-molded urethane case for field
  use

• Calibration automation and documentation
  with many popular third-party software
  packages

• Complies with CAN/CSA C22.2 No 1010.1-92,
  ANSI/ISA S82.01-1994, UL3111, and EN610-
  1:1993 

HART Protocol Features

• Universal, common practice and device specific commands

• Point-to-point and multi-drop operation

• Burst mode compatibility

• Read HART PV in digital mode

• Read and write HART configuration functions

• Read and clone transmitter configuration

• Re-tag smart transmitters

• Automated HART sensor and output trim

The MasterCAL 990 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 MasterCAL 990 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).

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.

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 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.

The MasterCAL 990 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.

Built-In Calculator Functions

The MasterCAL 990 features a built-in
calculator with square-root function, with
accessible registers containing measure and
source values.

Barcode Entry Options

The MasterCAL 990 will accept input from an optional barcode wand for rapid entry of instrument serial numbers.
