Alarm settings
If you press the ALARMS button momentarily, you can view each of the 4 alarm
settings (each press will illuminate in turn AL1, AL2, AL3 and AL4 LEDs).
Alarm settings are not locked out by the lockout switch.
To change alarm settings, select the alarm you wish to change as shown above
until its LED is flashing, then press the ALARM key for more than 3 seconds.
You will see one digit is brighter than the others. You can change its value using
the UP/DOWN buttons, and then select other digits with the DIGIT SELECT
pushbutton.
The alarm action is determined by the left-hand character. This will show an’H’
for HIGH alarm action, an ‘L’ for LOW alarm action, or a ‘o’ for NO alarm
action. You can change this with the UP/DOWN buttons. Press OK when set.
The HYSTERESIS value is identified with a ‘HY’ prompt, and you can change
this to suit your requirements, in the same way as the alarm value.
The hysteresis value is directly related to your measurements, so, for example, if
you have a high alarm, set to 500 , and set the hysteresis value to 7, the alarm
will occur when the meter reading rises above 500, and will reset when the
meter reading falls to 493 . If the hysteresis is set to 9999, the alarms will be
provided with ‘IN-FLIGHT’ compensation (automatic correction for overshoot)
