6.8.2 TRI – Trigger input
The parametrization of trigger input will be set with command TRI.
x edge parameterized the edge of trigger signal
0 rising edge (from LOW to HIGH)
1 falling edge (from HIGH to LOW)
2 every edge
y delay parameterized the time (delay) up to the measurement in milliseconds msec
Query:
TRI
Set:
TRI x y
Value range parameter x:
0, 1, 2
Value range parameter y:
0 to max 60 000 msec (equal to 1 minute)
active: from 1 msec upward
disabled: 0 msec
Standard:
0 0
Output: Trigger (input) [TRI]: 0, 0
Maximum frequency of external trigger signal: 1 Hz
If the trigger frequency is too high, no measurement value can be determined. The output is
E1203.
The trigger frequency must be reduced.

Parameter MF should be set ≠ 0 (for MF = 0 the measurement time is variable).
Voltage levels for trigger signals IN (load resistance 30 kOhm):
Low-Pegel < 1.3 V
High-Pegel > 1.3 V
Hysterese 0.1 V
