6.2. Selecting the baud rate of the RS232C interface (Default: 19200)
The speed of the data transfer for the RS232C interface can be adjusted to match
your data acquisition rate by changing the baud rate as follows:. This is possible
by changing the baud rate:
1. Switch off the instrument.
2. Press and hold RESET button.
3. Press the ON/OFF button.
4. Wait until f01 is displayed, then release RESET button.
5. Select function f04 by repeating to press the PEAK button until f04 is shown
on the display.
6. Press the MODE button repeatedly until the appropriate baud rate
(2400 / 4800 / 9600 / 19200) shows on the display.
7. Press the RESET button to save your settings.
6.3. Changing the up-date (refresh) rate of the display (Default: 3/sec)
The force applied to the load cell of the instrument is internally processed at a
rate of 1000Hz, which allows the precise capturing of the peak values. The read-
ings on the display, however, are refreshed at a default rate of 3 times/sec. You
may increase or decrease the factory settings to match your personal demands as
follows:
1. Switch off the instrument.
2. Press and hold the RESET button.
3. Press the ON/OFF button.
4. Wait until f01 is displayed, then release the RESET button.
5. Select function f02 by repeatedly pressing the PEAK button until f02 is
shown on the display.
6. Press the MODE button repeatedly until the desired refresh rate
(1 / 2 / 3 / 5 / 10 / 20 times/sec) appears on the display
7. Press the RESET button to save your settings.
6.4 Temperature Compensation (default: SET = on)
In general, it is recommended to have the this function turned on as long as it
does not effect your measuring results. Only when measuring very minute
forces over a longer period of time at a slow rate and under stable environmental
conditions might it be useful to switch this off.
1. Switch off the instrument.
2. Press and hold PEAK and MODE buttons.
3. Press ON/OFF button.
4. Wait until TRK oFF is displayed.
5. Release PEAK and MODE buttons.

8.2 Analog Output
The analog output (-1...0...1 VDC) can be used for any data acquisition or data
recording device. Pull Force data will be expressed as a negative voltage. The
signal can be set to zero (reset) by performing a ZERO (tare) function. +1 VDC
and – 1VDC refers to the maximum and minimum full scale (end of nominal
measuring range).
