Span adjustment applies for all sensors, including oxygen
sensors.
Use the <set> key to enter and follow the dialogue
2 o f 2
displayed.
The instrument shows which calibration gas is required for
the actual sensor type.
g a s !
The recommended concentration for span adjustment is
displayed. Default value is TLV concentration for the target
gas, 20 % LEL for catalytic sensors. When using calibra-
tion gas of a different concentration, change the value
accordingly. After the new value has been entered, actuate
the <set> key to continue.
Place the calibration cap over the sensor and start the
calibration gas flow (18 l/h or 300 ccm/min).
Actuate the <set> key to continue.
g a s !
Allow the reading to stabilize. If the reading matches the
concentration of the calibration gas, span adjustment is not
necessary. Actuate the <esc> key to exit.
If the reading does not match the concentration of the
calibration gas, actuate the <set> key to re-adjust the span
value and to continue the procedure.
?
The reading matches the concentration of the calibration
gas. Actuate the <set> key to proceed.
?
Actuate the <set> key to save the new span value and
store it in the unit's internal memory.
Stop the calibration gas flow. Remove gas and calibration
cap. Allow several minutes for the sensor to clear.
