Pass Code Protect: If the detector is pass code protected,
after a successful Auto Zero, the detector will prompt for the
pass code before proceeding to Auto Span and Alarm
Setpoints.
See the section “
Pass Code Protection ”.
Auto Span
Calibrate one, two, three or four sensors as desired.
The display shows
K
, prompting you to apply a calibration
gas to the sensor or skip the span (sensitivity adjustment):
2. Install the calibration cap and apply gas to the sensor at
a flow rate of 250 to 500 ml/min. Or, press
C
now to skip
the span.
When the detector senses approximately one-half of the
expected gas concentration (30 seconds), the audible alarm
beeps once. The detector then begins spanning the
sensor(s) (2 minutes).
The audible alarm beeps 3 times at the end of the span.
Remove the calibration gas.
Auto Span Sensor Fail
If a sensor fails, the display advises Err and skips the span
for the failed sensor(s). Other sensors span normally. Press
A
to exit, and then restart calibration in an atmosphere that
is clear of the targeted gases. If the auto zero fails a second
time, restart the detector to test the sensors.
Note: The detector will not span a sensor if:
• You do not apply gas to the sensor.
•
The sensor fails to detect at least one-half of the
expected gas concentration in the first 30 seconds.
•
The gas concentration drops below one-half of the
expected gas level during the 2 minute span.
If you apply gas to a sensor and the detector fails to span the
sensor, repeat the calibration process using a new gas
cylinder. If the sensor fails the span a second time, replace
