Ametek Jofra mACAL Loop Calibrator

The mAcal Milliamp Loop Calibrator is an economical, easy to
use calibration device for generating and measuring mA signals.
The instrument is especially designed for 2-wire transmitter
loops with 4-20mA signals and it is available with optional
NIST certification.

The unit’s compact size and light weight is ideal for field use.
Dedicated functions keys located on the front of the device
allow for simple, single-hand operation. The keypad provides
positive feedback to the user and each key is labeled for easy
operation. A large, high-contrast, 5-digit LCD display indicates
numeric values in mA, %, V or sec. Resolution is 0.001mA
in measurement mode. The user can change the display to
read in % of Full Scale. Flow readings are shown in % of Flow.
The display also indicates error codes. Alarms may be displayed
showing loop mismatch, reverse polarity and overrange.
The unit will also display low battery notification message. Plus,
the unit is equipped with an automatic shut-off features that
prevents accidental battery discharge. A built-in, permanent fuse
eliminates the need to replace the fuse in the case of overloads.

The mAcal Loop Calibrator provides loop power control in the
range of 0-45V and the instrument may be used to generate a
stable 24Vdc supply for the loop. The mAcal Loop Calibrator 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 and automatic steps with 10- or 30-seconds
between steps. For example, you can perform an entire test by
placing the mAcal Calibrator in the process loop and operating
from the control room.
