Traceable calibration

Allows for calibration of transmitters in a twowire loop

Internal 24 VDC supply for consistent
loop power

Read to 0.001 mA in the measurement mode

Displays a percentage to provide for easy
analysis of results

Fast one-key-one-function access to the
features such as the step function or loop
supply power

Includes large numbers for unit reading, a
percentage display, and dedicated icons for
calibrator status including a low battery
indicator

For your confidence, the unit is supplied with
a calibration certificate that is fully traceable
to a national standards lab such as NIST or
NPL

calibrators; including temperature sensors

The mAcal milliAmp Calibrator is an economical and easy-to-use calibration device for sourcing and measuring mA signals.
The instrument is designed specifically for 2-wire transmitter loops with 4
to 20 mA signals and it is delivered with traceable certification.
The keypad is easy-to-use and provides positive tactile feedback. Each
key is labeled for easy operation. A large, high-contrast, 5-digit LCD display indicates numeric values in mA, %, V or sec. The resolution is 0.001
mA in measurement mode. The user can change the display to read in %
of Full Scale and flow readings are shown in % of Flow.
The display also indicates error codes. Visual warnings are displayed for
loop mismatch, reverse polarity and over range. And is also equipped
with a user adjustable automatic shut-off feature that prevents accidental
battery discharge when the unit is not in use. A built-in, permanent fuse
eliminates the need to replace the fuse in the case of overloads: no need
to return the unit to the factory to reset or replace the fuse.

The mAcal provides loop power in the range of 0 to 45 VDC and the
instrument is designed to generate a stable 24 VDC supply for the loop.
The mAcal also reduces the time and complexity often associated with
loop calibration. The instrument features special fixed steps for performing linear and flow transmitter or valve positioner calibrations. The instrument has seven different built-in current values and the user may choose
between manual or automatic steps with 10 or 30 seconds between
steps. You can perform an entire test by placing the mAcal in the process loop and take readings from the control room.
