Characteristics
Input signal DC voltage/current, AC voltage/current
A/D conversion
method
Double integral method
Sampling period 50 Hz: 12.5 times/s; 60 Hz: 15 times/s (selectable)
Display refresh period Sampling period (sampling times multiplied by number of averaging times if simple average
processing is selected.)
Max. displayed digits 5 digits (–19999 to 99999)
Display 7-segment LED
Polarity display “–” is displayed automatically with a negative input signal.
Zero display Leading zeros are not displayed.
Scaling function Programmable with front-panel key inputs (range of display: –19999 to 99999). The decimal
point position can be set freely.
HOLD function Maximum hold (maximum data)
Minimum hold (minimum data)
External controls HOLD: (Process value held)
RESET: (Maximum/Minimum data reset)
ZERO: (Forced zero)
Comparative output
hysteresis setting
Programmable with front-panel key inputs (1 to 9999).
Other functions Variable linear output range (for models with linear outputs only)
Remote/Local processing (available for communications output models only)
Maximum/Minimum value data reset with front panel keys
Forced-zero set with front panel keys
Averaging processing function (simple or moving average)
Startup compensation time (0.0 to 99.9 s)
Comparative output pattern selection
