always return to this main display automatically.
Temperature is displayed on the upper-line of the display and the measuring unit on the
bottom line.
When "-------" is shown, then the value is too high to be displayed. The arrows indicate the
increase/decrease of the temperature trend.
Programming the temperature alarm values
Note: This function might not be accessible due to a configuration setting.
When the SELECT-key is pressed a few times, following temperature alarm values are displayed:
low temperature alarm: enter here 40 °C for example,
high temperature alarm: enter here 180 °C for example.
To change the alarm value, the following procedure must be executed:
1) press PROG: the word "PROGRAM" will flash or a pass code will be requested,
2) use to select the digits and to increase that value,
3) confirm the new alarm value by pressing ENTER.

4 - POWER MANAGEMENT
When used with the internal battery option, the user can expect reliable measurement over a long
period of time. The F043-T has several smart power management functions to extend the battery life
time significantly. Two of these functions can be set:
LCD NEW
41 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; the input signal will be
processed and the output signal will be generated in the normal way.
The following can be selected:
Fast - 1 sec - 3 sec - 15 sec - 30 sec - off.
Example battery life-time:
battery life-time with a FAST update: about 3 years.
battery life-time with a 1 sec update: about 5 years.
Note: 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.
BATTERY-MODE
42 The unit has two modes: operational or shelf.
After "shelf" has been selected, the unit can be stored for several years; it
will not process the sensor signal; the display is switched off but all
settings are stored. In this mode, power consumption is extremely low.
To wake up the unit again, press the SELECT-key twice.

5 - SENSOR
NR. OF WIRES
51 The PT100 element used can have 2, 3 or 4 wires. Do select the
appropriate type.
FILTER
52 The output signal of a sensor does mirror the actual temperature. This
signal is measured several times a second by the F043-T. The value
measured is a "snap-shot" of the real temperature as it will be fluctuating.
With the help of this digital filter a stable and accurate reading can be
obtained while the filter temperature can be set to a desired value.
The filter principal is based on three input values: the filter temperature
(01-99), the last measured analog value and the last average value. The
higher the filter value, the longer the response time on a value change will
be. Below, several filter levels with there response times are indicated:
