upwards triggers the meter alarm (BEEP). When the alarm is

triggered, the indication

ALARM

is displayed in the meter.

(Lowest setpoint of channel 1)

Determines a temperature value in channel 1 that when exceeded

downwards triggers the meter alarm (BEEP). When the alarm is

triggered, the indication

ALARM

is displayed in the meter.

(Highest setpoint of channel 2)

Determines a temperature value in channel 2 that when exceeded
