Response description
Command description
DATEZC?
yes
yes
DD.MM.YY
Returns date of the last span
calibration operation.
DATEZC DD.MM.YY
no
yes
DATEZC DD.MM.YY OK
or
DATEZC DD.MM.YY FAULT
Writes the last date of span
calibration to sensor memory
(DD – 00…31; MM – 0…12; YY
– 00…99).
INIT
no
yes
INIT OK
or
INIT FAULT
Resets sensor to the factory
calibration settings.
Use this
command only when sensor
atmosphere is filled with pure
air or high purity nitrogen. It
initializes zero and scale
coefficients setting them to one
(“1”).
After
sending
this
command, it is recommended
to check sensor readings. In
case if sensor does not comply
to
its
metrological
specifications, perform span
calibration (see Appendix D.1).
SETC XXXXX
yes
yes
SETC XXXXX OK
or
SETC XXXXX FAULT
Intended for determining the
current ambient temperature in
Celsius
degrees
(XXXXX
stands for degrees; i.e. 00023 =
23 °C). Sensor writes current
temperature ADC value to its
memory.
UPLOAD
no
yes
U_OK
By this command, sensor is set
to firmware updating mode.
This mode switches off auto-
matically upon the firmware is
updated. To switch it off manu-
ally reset sensor power supply.
ZERO
no
yes
ZERO OK
or
ZERO FAULT
Writes current temperature
ADC value and ratio S
t
value to
sensor controller memory by
this command.
ZERO0
no
yes
ZERO0 OK
or
ZERO0 FAULT
Erases temperature coeffi-
cients previously defined by
user.
ZERO2
no
yes
ZERO2 OK
or
ZERO2 FAULT
Intended for zeroing sensor. It
initiates calculation and storing
of the unifying zero coefficient
within sensor memory. C and
C
1
values are zeroed and ratio
S
tz
becomes equal 1 by this
command.
