Syntax Description
ENV [xtemp|xpres|xoxy|xhum]
[value] <cr>
Set new compensation values and store them in
RAM.
• xtemp = Compensation temperature. Range
-40 ... 100 °C.
• xpres = Compensation pressure. Range
500 ... 1150 hPa.
• xoxy = Oxygen content of background gas.
Range 0 ... 100%.
•
xhum
= Relative humidity of background gas.
Range 0 ... 100%.
Values of the parameters are stored in two places: EEPROM (non-volatile memory, values retained
during power off) and RAM (volatile memory that loses the values when probe is reset, and where
values are loaded from non-volatile memory at startup). As the number of writes to EEPROM is
limited to 30000 cycles by memory implementation, you must write all continuously updated
values to RAM to avoid wearing out the EEPROM.
Example (Show current compensation values; all compensations are enabled. Note that
temperature and pressure compensations use internal measurement, so the value in use is
constantly changing):
env
Temperature (C) : 37.00
Pressure (hPa) : 1013.20
Oxygen (%O2) : 19.70
Humidity (%RH) : 93.00
In use:
Temperature (C) : 23.10
Pressure (hPa) : 1011.28
Oxygen (%O2) : 19.70
Humidity (%RH) : 93.00
The following example sets temperature compensation to setpoint mode, and changes
temperature setpoint value to 37.2 in RAM.
pass 1300
tcmode on
T COMP MODE : ON
env xtemp 37.2
In eeprom:
Temperature (C) : 37.00
Pressure (hPa) : 1013.20
Oxygen (%O2) : 19.70
Humidity (%RH) : 93.00
In use:
Temperature (C) : 37.2
Pressure (hPa) : 1013.20
Oxygen (%O2) : 19.70
Humidity (%RH) : 93.00
