IMPORTANT:
Failure to test or calibrate the unit in
accordance with applicable instructions and with industry
guidelines may result in serious injury or death. The
manufacturer is not liable for any loss, injury, or damage
arising from improper testing, incorrect calibration, or
inappropriate use of the unit.
IMPORTANT:
Calibration should be done at least once per
year.
IMPORTANT:
In applications where life safety is critical,
calibration should be done quarterly (every 3 months) or on a
more frequent basis. Bacharach is not responsible for setting
safety practices and policies. Safe work procedures including
calibration policies are best determined by company policy,
industry standards, and local codes.
There are two concepts that need to be differentiated:
Bump Test
Exposing the sensor to a known concentration of target
gas and observing its response to the gas. The objective
is to establish if the sensor is reacting to the gas and all
the sensor outputs are working correctly. There are two
types of bump test.
•
Quantified:
A known concentration of gas is
used.
•
Non-Quantified:
A gas of unknown concentration is
used.
Calibration
Exposing the sensor to a calibration gas, setting the
“Standby voltage”, the span/range, and checking/ adjusting
all the outputs, to ensure that they are activated at the
specified gas concentration.
NOTE:
For improved accuracy and response, the instrument
should be zeroed and calibrated in the environment in which
it is being installed.
