ON TIME DELAY
Enter the time value in seconds that the output is delayed from turning on
after the trigger point is reached. A value of 0.0 allows the meter to update the
output status per the response time listed in the Specifications.

OFF TIME DELAY
0.0 to 599.9 seconds
Enter the time value in seconds that the output is delayed from turning off
after the trigger point is reached. A value of 0.0 allows the meter to update the
output status per the response time listed in the Specifications.
Enter the reset action of the output. See figure for details.
Auto = Automatic action; This action allows the output to automatically reset off
at the trigger points per the Setpoint Action shown in Setpoint Output
Figures. The “on” output may be manually reset (off) immediately by the
front panel
RST button or user input.The output remains off until the trigger
point is crossed again.
LAtCH = Latch with immediate reset action; This action latches the output on at
the trigger point per the Setpoint Action shown in Setpoint Output Figures.
Latch means that the output can only be turned off by the front panel RST
button or user input manual reset, serial reset command or meter power cycle.
When the user input or RST button is activated (momentary action), the

HYSTERESIS VALUE
1 to 59999
Enter desired hysteresis value. See Setpoint Output Figures for visual
explanation of how setpoint output actions (balanced and unbalanced) are
affected by the hysteresis. When the setpoint is a control output, usually
balanced hysteresis is used. For alarm applications, usually unbalanced
hysteresis is used. For unbalanced hysteresis modes, the hysteresis functions on
the low side for high acting setpoints and functions on the high side for low
acting setpoints.
Note: Hysteresis eliminates output chatter at the switch point, while time delay
can be used to prevent false triggering during process transient events.
