SYMPTOM PROBABLE CAUSES AND REMEDIES
The instrument does not work at all. Pushing the
button the instrument does not turn on.
a. Press the for at least 2 seconds.
b. The battery is low; connect the battery charger to the
instrument.
c. The battery pack is not connected to the instrument.
Access the internal parts of the instrument and verify
that the connector of the battery pack is inserted in
the proper connector ( SEE CHAPTER 16.4 ).
d. The instrument is faulty: send it to a service center.
The battery symbol is empty on the inside and blinking.
The batteries are low. The instrument will remain on for
a couple of minutes after which it will switch off;
connect the battery charger.
The instrument battery performance is lower than what
stated in the “ Technical features ” chapter.
a. The battery capacity is limited at a low temperature.
To obtain a greater performance it is advised to
keep the instrument in higher temperatures.
b. Perform a 100% complete charge cycle connecting
the instrument to the plug for at least 6 hrs.
c. That battery pack is old. Aging can cause the
batteries to reduce their capacity. If the performance
has become unacceptable change the internal
battery with an original part Yellow Jacket.(68623)
d. Verify the measured voltage values in
“ Menu → Diagnostic → Hardware → Voltages ”:
- If VBAT<3000mV: the battery needs to be changed.
- If VIN <4700mV: the output voltage of the battery
charger is not sufficient to recharge the instrument
battery. In this case verify the connections and the
plate data of the battery charger in use: 5Vdc 2A.
d. If the problem keeps on happening contact the
SERVICE CENTER.
Date and time are not memorized.
a. Verify the voltage value VRTC showed in
“ Menu → Diagnostic → Hardware → Voltages ”:
If <2600mV contact the SERVICE CENTER.
b. The battery is completely drained (VBAT<2500mV)
After the autozero, the sensor diagnostic screen
appears, which indicates an error in one or more cells.
a. The autozero has been performed while the
combustion gas sample was still being taken.
b. The O
2
sensor is broken, incorrectly connected or
not connected at all. Check the described points,
with the help of the paragraph 5.3, 5.4, 6.6.
c. The waited settling time of the sensor was not
enough or the instrument has been left with a low
battery charge for a long time.
In the Pressure / Draft screen there is an error of the
pressure sensor.
There is a calibration problem.
Send the instrument to the service center.
In the analysis screen there is an error in the smoke
temperature measurement (Tf).
a. Thermocouple not connected; connect the
thermocouple to the analyzer.
b. The sensor has been exposed to temperature higher
or lower than its functioning.
c. The thermocouple is faulty. Send the entire probe to
the service center.
