currently selected decimal point position. Use the
between: NO DP, 0.1, 0.12, 0.123, or 0.1234, and then press

currently selected display rounding. Using the
2, 5 or 10, and then press
Rounding is quoted in display counts and is not influenced by decimal point position. For
example, if your input signal is 5.3mA, the display will show: 5.3 (for rounding=NONE), 5.4 (for
rounding=2), 5.5 (for rounding=5) or 5.0 (for rounding=10).

Calibration
WHEN CALIBRATION IS COMPLETE, YOU WILL BE DIRECTED BACK TO THE OPERATIONAL
DISPLAY. TO PROCEED TO 5.4, YOU MUST SELECT SKIP AT 5.3A. THIS UNIT HAS BEEN
FACTORY CALIBRATED FOR 4-20MA.
A _ _ _ CALIBRATION TECHNIQUE
SKIP. Press
MAN (manual) or S.G. (specific gravity), and then press
AUTO - The automatic (key-in) 2-point calibration procedure uses zero and span values to
calculate the scale and offset. This is the most accurate calibration method, but requires known
low and high input signals (or the use of a calibrator).
MAN - The manual calibration procedure uses low and high display values, and is intended for
a pre-calibrated sensor with a known output range. (For example 4mA=0 and 20mA=1000.) It
does not require any input signals to be applied to the controller during calibration.
S.G. - The specific gravity calibration procedure allows the user to enter a scale factor which is
used to compensate for changes in the specific gravity of different substances. This does not
constitute a full calibration and assumes that either an automatic or manual calibration has
been applied previously with the S.G. value set to 1.0.
