6.1.5.2.2 Setup > Alarms > Alarm Limits > AC VOLTAGE LIMIT
Use this function to set the voltage levels at which the "AC VOLTAGE HIGH" and AC VOLTAGE
LOW" alarms will be activated.
You can also set a "hysteresis" value. This value damps the sensitivity of the alarms to prevent a
situation where, for example, a minor but frequent fluctuation of 1 Vac just above or below the
threshold value causes an ac voltage alarm to turn on and off many times, rapidly.
The hysteresis value is the number of volts that a measurement must change before an alarm
senses that the measurement has changed. So, in the example above, if you set a hysteresis
value of 2, the alarm state wouldn't change until the fluctuation grew to 2 Vac. This would reduce
the number of alarms while still ensuring that an alarm will be sounded when the voltage meets
the threshold.
6.1.5.2.3 Setup > Alarms > Alarm Limits >TEMPERATURE LIMITS
This function lets you set the temperature (in °C) at which the high-temperature alarm and low-
temperature alarm are generated. The temperature is read from an optionalinternal temperature
sensor.
