8. Maintenance
1.
DO a regular battery checkup and recharge it fully before use whenever the battery is low.
2.
Perform the calibration check once in a month. Calibration check every month will ensure
the accuracy of readings throughout the life of the instrument.
3.
NEVER allow the unit to be used in direct sunlight. You may provide the canopy/sun shade
while using the instrument on the site.
4.
ZERO it in a target gas-free clean air.
5.
NEVER expose the sensor to gas concentration higher than its prescribed range.
6.
DO NOT expose the monitor to excessive positive or negative pressure. It affects the
accuracy of the measurement.
7.
Occasionally, the casing of the instrument can be cleaned with a slightly damp lint free
cloth. Wipe the instrument thoroughly dry using a fresh lint free cloth. But care should be
taken not to allow any water or moisture to enter the instrument.
8.
Do not keep the monitor without use, for more than 3 months (from the date of
shipment). Li-Ion battery performance may get affected.
