Upper limit of regulated parameter value (parameter code “22:”) and lower limit of regulated
parameter value (parameter code “23:”), also valve runtime (parameter code “24:L” and regulation speed
(pause intervals between opening the valve, after each 1 % of valve run time
– parameter code “25:P”)
can be modified if required, as described in Paragraph 7.
To return to instantaneous parameter display mode (“INT”) press and hold button

.
Parameter codes, meanings and allowed regulation limits are provided in Appendix A.
8.7. Activating test mode
8.7.1. Test mode is used for quick testing of calculator. When test mode
is activated (“TEST” label displayed), calculation process is stopped and all
integral parameter values are stored in the memory. Calculation process
starts again after leaving test mode.
8.7.2. Activating test mode
After opening the lid, briefly press the programming button “SET”.
Calculation unit enters programming mode, label “SET” is displayed on the
upper part
of LCD together with the message “
test: off
”. By long pressing
the control button

activate test mode (message “
test: on
” appears on
LCD). When programming button “SET” is pressed, the device enters test
mode
– label “TEST” appears on the upper part of LC

will imitate flow pulses, directly
relevant to fluid volume V1…V4 (The values of the volume can be seen on
the indicator in the end of the test). According to really measured
temperature values, energy is calculated, and output pulses are generated.
Calculation duration
–
100 s (During the test on the indicator the message
"TEST" is blinking).
All parameters are displayed on LCD in the same way as in the main
menu, only integral values are calculated starting from zero.
Press the programming button “SET” once more to leave test mode.
After leaving test mode, previously recorded integral parameter values are
displayed.
8.8. Remote data transmission
8.8.1. For data transmission from the calculator to the data reading device can be used the optical
interface (optical head is placed on the front panel of the calculator , as shown in Figure 8.6, and is
connected to interface RS-232 of data reading device) or other wired serial interface (depending on type
of the completed module of communication under table 7) .
8.8.2. As the reading device it is possible to use the computer, the telephone modem, modem
GSM, the Internet modem and so on.
Scheme of direct connection of calculator to interface RS-232 of PC is presented in fig.6 of Annex
B. Scheme of direct connection of calculator to interface RS-232 of modem or printer in fig.7 of Annex
B.
The data reading rate and parity (it is switched off or even) on the data reading device should
correspond to established on the calculator
8.8.3. By using the serial communication interface it is possible to perform:
In normal mode:
- To read out all measured data and the data from calculator archive
- To read out and change the settings of regulator
- To read out the configuration settings of calculator.
In parameterization mode "SET" (this can be activated by pressing the button "SET"):
