Scaling: -9999 to 9999

PV indication: Output signal in engineering unit

Overrange indication: LEDs blinking

Power saving mode: Displays turn off if the keys are

untouched for a preset time period

LEDs: Red; the PL1 turns on with negative polarity, the PL2

turns on at MANUAL mode, the PL3 turns on when UP signal

on at MANUAL mode, the PL4 turns on when DOWN signal

on at MANUAL mode.
