3.3.3 EXPLANATION OF SETUP-MENU 2 - ALARM
SETUP FUNCTIONS AND VARIABLES
2 ALARM
2.1 ALARM VALUE LOW
TEMPERATURE
The low alarm is set with this setting. An alarm will be generated as
long as the temperature is lower than this value.
With value 0.0 this function is disabled.
2.2 ALARM VALUE HIGH
TEMPERATURE
The high alarm is set with this setting. An alarm will be generated as
long as the temperature is higher than this value.
With value 0.0 this function is disabled.
2.3 DELAY TIME ALARM
LOW TEMPERATURE
An alarm generated by SETUP 2.1
“low” can be ignored during X-time
period. If the actual temperature is still incorrect after this delay time,
then an alarm will be generated.
2.4 DELAY TIME ALARM
HIGH TEMPERATURE
An alarm generated by SETUP 2.2
“high” can be ignored during X-
time period. If the actual temperature is still incorrect after this delay
time, then an alarm will be generated.
2.5 ALARM OUTPUT
TRANSISTOR /RELAY
One transistor or relay output is available to transmit the alarm
condition. Assign with this function the type of alarm to be transmitted:
low temperature alarm, high temperature alarm or both alarms.

period of time. The F043-T has several smart power management functions to extend the battery life
time significantly. Two of these functions are available.
SETUP FUNCTIONS AND VARIABLES
4 POWER MANAGEMENT
4.1 LCD NEW
The calculation of the display-information influences the power
consumption significantly. When the application does not require a
fast display update, it is
strongly advised to select a slow refresh
rate. Please understand that NO information will be lost; every pulse
will be counted and the output signal will be generated in the normal
way. The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - off.
Example battery life-time:
•
FAST update: about 3 years.
•
1 sec update: about 5 years.
After a button has been pressed by the operator - the display refresh
rate will always switch to FAST for 30 seconds. When "OFF" is
selected, the display will be switched off after 30 seconds and will be
switched on as soon as a button has been pressed.
