mAcal - mA Loop Calibrator
The JOFRA mAcal keypad is easy-to-use and provides positive tactile feedback to the user. 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. Plus, the unit is 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 Loop Calibrator 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 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 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.
