The user can select

RESULT

(moisture),

DP_C

(dew point °C),

TEMP_C

(temperature

°C),

DP_F

(dew point °F) or

TEMP_F

(temperature °F) as the alarm source.

Other

options like DISP and TOT_1 in the list are for factory settings only and should

not be changed

a. Use the



and



keys to adjust the control code to

CAUTION: The Alarm Set-Point value will NOT be converted automatically

based on the new alarm source selected. In some cases, the operation to

change the alarm source may trigger the alarm.

For example: If the SP_1 is set

at 10ºC dew point - when the alarm source is changed from

DP_C

(ºC dew point) to

DP_F

(ºF dew point) under SPC_1, the value of SP_1 will be 10ºF.
