Calibrating the Device
41
SCOTT SAFETY
087-0038 REV L
Equipment required:
•
Calibration gas – Verify concentration level matches detection set points of
monitor and expiration date of cylinder has not passed.
•
Tygon tubing – 2 feet of 3/16" ID
•
Regulator – Set to provide flow at 0.5LPM
•
Calibration Adapter – Included with the device
Caution:
Gas must be applied at a flow rate of 0.5LPM to perform Span Calibration.
Failure to apply gas at the proper flow rate results in failed or inaccurate calibration.
The device can be Span Calibrated using either individual calibration gas cylinders
that contain one specific target gas for the sensor being calibrated or a gas mixture
cylinder that contains a mixture of each of the target gases required to calibrate each
of the sensors the device is presently configured to detect. If using individual gas
cylinders to Span Calibrate, the Span Calibration procedure must be completed for
each sensor.
The device has an automatic 80 second timer that is enabled when APPLY GAS screen
is displayed. If you are unable to apply gas to the sensors within the 80 seconds, CAL
STOPPED displays. Pressing the right or left operational button exits calibration
mode and the procedure must be repeated.
1
Verify the concentration level of the target gas in the cylinder matches the settings
of the device as set using the SGM software. See
If needed.
2
Attach the Regulator to the gas cylinder and verify cylinder pressure.
3
Connect Tygon tubing to both the Regulator and calibration adapter.
4
With the device powered on, and if not already accomplished, press and hold the
Right Operation Button until the Zero Calibration completes and APPLY GAS or
the optional password entry screen displays on the LCD.
If optional password screen is displayed, perform
.
5
If needed, enter the 4-digit password using the Left Operation Button to scroll
through the numeric characters and the Right Operation Button to accept the entry
and move to the next character.
CAL STOPPED displays if longer than 30 seconds has passed between character
entries. Press either the left or right operation button to exit calibration mode and
restart procedure.
6
Attach the Calibration Adapter to the device and apply gas from the Regulator. See
.
