15. Temperature sensor offset (t
r0
)
Temperature sensor offset (tr0) can be adjusted in the SETUP loop. Depending on the calculator’s configuration, this
function can be disabled and the menu item will in that case display “OFF”.
Offset can be adjusted in the interval -0.99…0.99 K. Pressing the primary key, the 0 and the sign start flashing and it
is now possible to switch between – and +, indicated in the display by the fact that the minus sign flashes and
switches of respectively. Use the arrow keys to shift to the digits to the right of the decimal point, i.e. it is not
possible to change the value of the first digit as the valid interval is -0.99…0.99 K. Both the first and the second
decimal can be set to a value between 0 and 9. Read more about temperature sensor offset in paragraph 7.3.
Note: The set offset is active for all temperature sensors connected to MULTICAL® 803, i.e. both t1, t2, t3 and t4.
16. Radio on/off
The calculator’s radio/wireless communication can be adjusted to being switched on or switched off. The calculator
automatically turns on the radio when the calculator leaves the transport state, i.e. when the calculator has detected
a flow of 1 % of qp or greater. The radio on/off function in the SETUP loop is primarily used for switching on the radio
in transport state without the calculator having registered a flow as well as for switching off the radio when the
calculator is dismounted after having been in operation, e.g. if it is to be sent by airfreight. The calculator’s present
condition is indicated by two symbols in the bottom left corner of the display.
The above definition of the radio on/off symbols simplify the use of radio on/off in the SETUP loop too as it is
possible to switch between radio on and radio off regardless of whether a module is mounted in the calculator or
not. This offers flexibility that enables a utility company to configure the calculator prior to mounting a module and
thus to make sure that radio is either by default switched on in transport state or switched off when the module is
subsequently mounted.
Be aware of setting the required offset adjustment, not the error of the temperature sensor pair.
If the selected temperature sensor pair contributes with an error of -0.20 K, the meter’s offset must be set
to 0.20 K.
IMPORTANT:
- If the meter’s radio communication is switched off via the SETUP loop, the calculator
subsequently switches on radio communication again the first time it registers a flow of 1 % of
qp or greater.
-
The symbols for radio on/off indicate whether the meter allows radio communication, not
whether a radio module has activated its radio communication. Be aware of this when
troubleshooting the meter’s wireless communication.
