OdaLog Portable Gas Loggers
Safety Precautions | 5
Before each deployment, sensitivity must be
tested on a known concentration of test gas (to
match the sensor type) equivalent to 20-50
percent of full-scale concentration. Accuracy
must be within ±10% of actual concentration or
±5% of full scale. Accuracy may be corrected by
calibration (refer to user manual for calibration). It
is recommended that a gas check be performed
after deployment as well, so that accuracy of
logged data can be checked.
(and corrected if necessary in the software.)
Battery shall not be removed or replaced by user
for any maintenance. Contact manufacturer /
authorized distributor.
Only touch the instrument with an insulating
object.
To avoid build-up of electrostatic charge, the
instrument shall be used or placed where it will
be protected from inadvertent rubbing and shall
only be cleaned or wiped with a damp cloth
when used in explosive atmospheres.
Only use the micro-SD card that is provided or
recommended by the manufacturer.
The enclosure shall only be disassembled in the
non-hazardous area.
The following parameters shall be taken into
account during interconnection in a system:
Odalog G20 RTX Entity Parameters at Connector
CN6:
Uo 3.9 V
Io 275 mA
Lo 55.77 µH
Co 22 µF
Ui 3.7 V
Pi 206 mW
Ci 181 µF
Li 17 µH
The maximum external capacitance and
maximum external inductance of the circuits
connected at CN6 have been additionally
assessed for spark ignition compliance with
resistive current limiting circuits at elevated
voltages and currents and found to be compliant
as follows:
U
7.6 V
I
518 mA
Co
203 µF
Lo
