4: Normal Operation
Model TX-KE and TX-KP gas detectors are designed for use with a PureAire
controller or other control system capable of receiving a 4-20 mA signal.
During normal operation, the instrument will display the measured gas
concentration on its local analog or digital readout and output a corresponding
4-20 mA analog signal.
4.1 Concentration Display and Power Indicator Lamp
NOTE: The following applies to both the Model TX-KE and Model TX-KP.
4.1.1
Concentration Display
This is a real time display of the measured concentration of the target gas. The
target gas and units of measure (PPM, PPB, etc.) are indicated on the front of the
instrument.
4.1.1
Power LED
This LED is lit when the instrument is operating properly. It will get brighter as
the measured gas concentration increases.
4.2 Routine Maintenance Schedule
Continuous gas detection systems depended upon to measure and detect
hazardous gas leaks require periodic maintenance to ensure proper operation. The
frequency with which this routine maintenance is required depends on the
environment, since temperature, humidity, gas concentrations, and dust all affect
system operation.
The following table is intended to serve as a general guideline for routine
maintenance. The conditions in your particular application, as well as your
organization’s maintenance policies, will ultimately determine the best routine
maintenance schedule for your equipment.
4.2.1
Routine Visual Checks
Items to check
Check for power and proper operation
Condition / status when
operating properly
Should read “0” when no gas is present; analog
output signal at 4 mA.
Corrective actions

Zero Calibration
IMPORTANT: This procedure should be performed under normal monitoring
conditions, without any of the target gas present.
1. Check the instrument’s gas concentration reading on the local display.
2. If the display does not read a steady “0,” adjust the zero potentiometer as
required. Note: Depending on the gas sensor a clockwise or counterclockwise
rotation increases the value; a counterclockwise or clockwise rotation decreases
the value.
 NOTE: On units shipped through Nov 2008, the digital display does not
display a negative sign. The lowest zero setting will indicate 0.02 or 0.2ppm.
When adjusting zero, turn the pot until the display reading increases, and then
turn it back down until the reading indicates 0.00 or 0.0. This will insure that
you are in the positive range of the display setting.
 Units manufactured in 2009 display a negative sign.
5.2.3
Span Calibration
CAUTION: Be sure to observe all safety guidelines when generating and using
calibration gases.
NOTE: Gas generation kits are available through PureAire. These kits include
instructions and materials for generating calibration gases and precise methods
for accurately measuring the concentration of these gases.
NOTE: The gas concentration should be close to, but never exceed, full scale.
1. Connect the appropriate calibration cap to the inlet of the high flow sampling
pump and connect the Tedlar “waste gas” bag to the outlet of the pump.
2. Open the valve on the waste gas bag.
3. Connect the flowmeter to the inlet of the calibration cap and turn the high
flow sampling pump “on.”
4. Adjust the pump’s flowrate potentiometer until a flowrate of 0.5 liters/minute
(0.2 liters/minute for hydride sensors) is achieved. A clockwise rotation
increases flow; a counter-clockwise rotation decreases flow.
5. Recheck the instrument’s zero reading; adjust as required.
6. Generate the calibration gas within a Tedlar bag.
IMPORTANT: Be sure to perform the calibration before the concentration of
the gas changes. Also, PureAire recommends that you verify that the
concentration of the calibration gas is the same after calibration as it was before.
7. Disconnect the flowmeter and connect the Tedlar calibration gas bag to the
inlet side of the calibration cap.
8. Open the valve on the calibration gas bag.
9. Expose the sensor cell to the span gas for 1 to 2 minutes until the gas reading
stabilizes.
16
PureAire Monitoring Systems, Inc.
2/22/2000
11. Adjust the instrument’s span potentiometer until the displayed gas reading
matches the concentration value of the calibration gas. Note: Depending on
the gas sensor a clockwise or counterclockwise rotation increases the value; a
counterclockwise or clockwise rotation decreases the value.
10. Close the valve on the calibration gas bag and permit the instrument to return
to a zero reading.
11. Open the valve on the calibration gas bag and verify that the display reading
matches the concentration of the calibration gas. Readjust the span
potentiometer as required.
12. Close the valve on the calibration gas bag and disconnect it from the
calibration cap.
13. Allow the instrument to return to a zero reading. If the instrument has not
returned to zero after 5 minutes, readjust the zero potentiometer as required.
14. Close the valve on the waste gas bag and disconnect from the sampling
pump.
15. Turn the sampling pump “off.”
16. Carefully remove the calibration cap from the sensor cell.
IMPORTANT: Do not twist the calibration cap for D-type or renewable sensor
cells.
17. Replace the calibration port cover.
18. If the instrument is connected to a controller, return the controller to the
monitoring mode.
WARNING: Be sure to dispose of the remaining calibration gas and waste gas
properly.
