3. CALIBRATION CHECK
Every three months check the Temperature, Humidity and Oxygen probes correct operation.
To check the probes reading use the optional Ginevri Reference Simulator P/N 10487A60.
To check the reading of the probes perform the following steps:
Temperature probes
a) Switch off the equipment and disconnect it from the mains
b) Disconnect from the control panel the probe assembly connector and replace it
with the Reference Simulator
c) Connect the equipment to the mains and switch it on
d) Select on the Reference Simulator: PROBES on AIR 1
TEMP °C on 25°C
SELECT on MUTE
The AIR LED display should show the selected reading with a ±0.2°C tolerance
for temperatures lower then 30°C and with a ±0.1°C tolerance for temperatures
higher then 30°C.
Repeat this step for the temperature settings
e) Check the AIR2 and SKIN Temperature probes selecting AIR2 first and then
SKIN on the simulator dial and performing the same operations of the preceding
step
f) Select on the Reference Simulator: PROBES MAX TEMP
TEMP °C on 39.8°C
SELECT on H.T.
check that the MAX TEMP alarm does not activate.
Select on the Reference Simulator: TEMP °C on 40.1°C And check that the
MAX TEMP alarm activates.
Humidity Probe
a) Switch off the equipment and disconnect it from the mains
b) Disconnect from the control panel the probe assembly connector and
replace it with the Reference Simulator
c) Connect the equipment to the mains and switch it on
d) Select on the Reference Simulator: PROBES on HUM
Hum % on 30%
SELECT on MUTE
e) The HUM LED display should show the selected reading
f) Repeat this step for all Hum %settings .
Oxygen probe
a) Switch off the equipment and disconnect it from the mains
b) Disconnect from the control panel the probe assembly connector and
replace it with the Reference Simulator
c) Connect the equipment to the mains and switch it on
d) Select on the Reference Simulator: PROBES on OXY
Oxy % on 21%
SELECT on MUTE
e) The OXY LED display should show the selected reading
f) Repeat this step for all the OXY %settings
If the readings of the probes are not correct, within the specified tolerances, the probes should
be calibrated. The calibration is performed by means of the reference simulator as described in
the following chapters.
