A programmed alarm must be set to "ON" to function properly (general activation
or deactivation of alarms is generated in the alarm mode). Modifying one or sev-
eral characteristics of an alarm set to "ON", automatically switches it to "OFF".
ITEM
FUNCTION
1.
Hysteresis Percentage (1, 2, 5 or 10%). A hysteresis value is set to prevent multiple
recordings of an event that goes above the threshold and a certain percentage below
it at times.
Example: If the alarm threshold is 100V or higher, the hysteresis is 1%. When the
voltage goes up to 100V, the alarm condition starts, when it goes back down to 99V,
the alarm condition stops.
2.
Alarm number (1 to 10)
3.
Alarm activation (ON or OFF)
4.
The target of the alarm (Vrms, Arms, VPST, Vcf, Acf, Hz, Akf, Vthd, Athd, W, VAR, VA, DPF,
PF, Tan, Vh, Ah or VAh)
5.
Threshold value for triggering an alarm
6.
Minimum duration from beginning threshold detection to store the alarm (from 0.01
seconds to 99 minutes)
7.
Less than "<" or greater than ">"
NOTE: When the alarm is "OFF", the parameters previously used are stored in
memory and reappear if the alarm is selected again.
