current when using the current outputs) to represent a particular range.
The following table gives the range ID output for each analysis range:
Table 4-2: Range ID Output Voltage
Range Voltage (V) Current (mA)
LO 0.25 8
MED 0.50 12
HI 0.75 16
CAL (0-25%) 1.00 20
IMPORTANT: In the event of loss of flow through the analyzer, if
the vent is vented to a location of high oxygen
content, oxygen will back diffuse through the vent
line and enter the cell. For the standard B-2CXL
Micro-fuel Cell this can saturate the cell with
oxygen and require a long purge down time before
the sensor can recover. This is less of a problem
when using the Insta-Trace sensor which is
specifically designed to allow rapid recovery from
accidental high oxygen exposures.
In the event that flow is to be interrupted into the
analyzer, it is suggested that the user do one of the
following:
1. Bag the sensor in nitrogen during this time
2. Install a shut off valve on the vent port of the
analyzer or somewhere within the users
sample system.
3. Retrofit the instrument to use the Insta-Trace
Micro-fuel Cell (see Section 3.4)
