Gas Calibration
Span Adjust
Span adjustment applies for all sensors, including oxygen
sensors.
Use the <set> key to enter and follow the dialogue
displayed.
<Actual Calibration Gas>
The instrument shows which calibration gas is required for
the actual sensor type.
<Actual Concentration for Calibration>
The recommended concentration for span adjustment is
displayed. Default value is TLV concentration for the
target gas.When using calibration gas of a different
concentration, change the value accordingly.
After the new value has been entered, actuate the <set>
key to continue.
Apply Gas !
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.
<Actual Span Value>
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.
<Re-adjusted Span Value>
The reading matches the concentration of the calibration
gas. Actuate the <set> key to proceed.
Save ?
Actuate the <set> key to save the new span value and
store it in the unit's internal memory.
Remove Gas !
Stop the calibration gas flow. Remove gas and calibration
cap. Allow several minutes for the sensor to clear.
