Tracking width :0.0 to 9.9 (d)
￭
Power on zero function
Sets the zero state at power on.
￭
Digital filter function
Cutoff frequency range: 0.7 to 11 (Hz)
￭
Comparator function
HI, OK or LO is determined by setting the upper or lower limit value.

￭
Latch function
Perform latching of the displayed value, comparator output, analog output, serial
output, using the external LATCH input.
￭
Relay output function (option)
Provides contact output of the HI, OK or LO signals.
￭
Serial input and output function (option)
The RS-232C/RS-485 option can output measured values and input commands.
