extra zero may be switched
on to d/- 19,999(0). Leading zero
blanked.
DECIMAL POINT
Decimal point may be placed in any of the
following positions. 1.9999, 19.999,199.99,
1999.9, 19999 or 199990 with extra zero.
CALIBRATION
4 mA (1 V) input may be set anywhere in range
RANGE
of the meter. 20 mA (5 V) may be set anywhere
in range of the meter above or below 4 mA
input. An Error message will appear if Input 1
signal and Input 2 signal are too close together.

INPUT
Voltage ranges, greater than 300 Kohms;
IMPEDANCE
current ranges, 100 ohms.
LOOP POWER
(AC Meters only), Isolated 24 VDC ± 5% @ 20
mA regulated. Maximum loop resistance is
1200 ohms. Available for either signal input or
4-20 mA output, but not both.
HOLD READING

ACCURACY
±0.05% of calibrated span, ±1 count.
SQUARE ROOT
±0.1% F.S. ± 1 count from 10-100% of flow.
EXTRACTION
LOW FLOW
Any input below the Low-flow Cutoff point will
CUTOFF
result in a display of zero. May be set from 1
count to 100% of full scale, user selectable.

LINEARIZATION
Between Inputs
4-20 mA
(1.6 mA / (Number of points –1))
0-5 V
(0.16 V / (Number of points -1))
0-10 V
(0.32 V / (Number of points -1))
e.g. Minimum span for an 11-point, 4-20 mA calibration is 0.16 mA between inputs.
ALARM POINTS
Four, any combination of high or low alarms.
ALARM POINT
0-100% of full scale, user selectable.
DEADBAND
ALARM STATUS
Front panel LED.
