I/O OPTIONS
■ Event Trigger Input: Dry contact or NPN open collector
Input current: ≤ 3 mA
Sensing: 6 V
Contact detecting: ≤ 1.5 V at ON; ≥ 3 V at OFF
Signal ID and Details
S-TMR: Startup Timer
Measuring starts in the predetermined time after detecting
the signal turning on.
TIMING: Timing
Used for various timing hold functions
ZERO: Forced Zero
Forced Zero and tare adjustment are externally controlled
when ZERO signal is turned on/off.
HOLD: Hold data
Reading measured signal stops and the last
value is held when HOLD signal is turned on.
RESET: Reset data
The device is reset when RESET signal is turned on.
