Display 6 Digit high efficiency red LED, -19,999(0) to 29,999 (0) with selectable extra zero. Total: 0 to 999,999.
Automatic lead zero blanking
Decimal point Process/rate display: Decimal point may be placed in any of the following positions. 2.9999, 29.999, 299.99, 2999.9 or 299990. Total decimal point: 9.99999, 99.9999, 999.999, 9999.99, 99999.9.
Rate and total decimal points are independent of each other
Calibration range 4 mA (1 V) input may be set anywhere in rage of the meter. 20 mA (5 V) may be set anywhere in rage 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 Range Minimum Difference Between Input 1 & Input 2:
0-5 V 0.16 V
0-10 V 0.32 V
4-20 mA 1.60 mA
Input impedance Voltage ranges, greater than 300 kΩ; current ranges, 100 Ω
Loop power Two isolated power supplies, 24 VDC ±5% @ 20 mA each, regulated. Maximum loop resistance is 1200 Ω
Linear input accuracy ±0.05% of calibrated span, ±1 count
Root extraction accuracy ±0.1% F.S. ±2 counts
Programmable exponent From 1.0001 to 2.9999
11 Point Linearization
Input Range Minimum Span 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 deadband 0-100% of full scale, user selectable
