Routine Maintenance 82 5 ISP-074-575-P1D 82
Battery Charging A fully charged battery pack powers the 2020ComboPRO for approximately 6 hours. If the instrument is to be used for more than 6 hours, carry a spare battery pack (Part No. MX700010 or MX700011). When the first one has been discharged, replace it with the spare. NOTE: If you do not turn off the 2020ComboPRO before removing the battery pack, you will reset the instrument and you will lose all logged data and setup parameters.
Battery Pack Care Leaving the 2020ComboPRO for more than 3 months without charging the batteries may result in the loss of recorded data and setup parameters. If the 2020ComboPRO will not be used for long periods of time, recharge the battery for a few hours every 30 days to avoid loss of data. See Battery Charging on page 39 for instructions on charging the battery. Please observe the following: For replacement battery pack use only Part No. MX700010 or MX700011.
2. Remove the lamp housing cover using the multi-tool. 3. Tilt the 2020ComboPRO slightly and remove the UV lamp. Do not touch the wire grid inside the detector cell. Any dust or dirt in the detector cell can be blown out with a gentle jet of compressed air. Do not insert any object, other than the UV lamp, into the lamp holder. CAUTION 4. Without touching the lamp window, place the new lamp into the 2020ComboPRO lamp holder, window first. See Figure 26. Figure 27.
eventually evaporate off the window, but it will usually leave a residue that must be removed by cleaning the lamp window. Since some UV inhibiting deposits are invisible to the eye, regular cleaning of the lamp window is strongly recommended. Clean the lamp frequently to prevent a heavy buildup of deposits that may be difficult to remove. Do not remove the UV lamp in a hazardous location. WARNING The UV lamp cleaning kit (Part No. MX380336) includes aluminum oxide powder (3.
5. Continue cleaning for approximately one minute. 6. Dampen a new cotton swab with methanol and remove any trace amounts of the cleaning compound from the lamp window. 7. Wipe the window and the lamp with a dry, lint free tissue to remove any trace amounts of the cleaning compound and methanol. All traces of cleaning compound must be removed. 8. If you removed an O-ring from the lamp, replace it now. Ensure your hands are clean and dry. 9.
To replace the inlet filter: 1. Turn off the instrument. Unscrew the filter housing from the detector housing. Be careful not to lose the O-ring seal. 2. Remove the Teflon®/Polypropylene filter and install the new filter (Part No. MX750100). Place the filter so that the Teflon side is facing down in the filter housing and the mesh side is facing the 2020ComboPRO. Figure 28. Replacing the Inlet Filter Handle the filter disk only by the edges. The mesh may be damaged or contaminated by excessive handling.

UV Lamp Error UV lamp window is dirty. Clean the lamp window. See page 80. UV lamp is failing. Install a new lamp. See Removing and Replacing the UV Lamp on page 84. The concentration and sample gas are not compatible with the 2020ComboPRO. Contact INFICON. UV lamp has not started immediately. This fault may occur momentarily when the 2020ComboPRO is first turned on. Allow 60 seconds for UV lamp to start and fault to clear. Turn the 2020ComboPROoff then on again.
Instrument over range 92 High concentrations of gases will saturate the detector and electronics. Wait until the display returns to normal. PIDs are designed to detect relatively low levels of gases. The detector has become saturated. Move the 2020ComboPRO to a location where it can sample clean air. Sample clean air until the readings stabilize at a low level. Detector has been shortcircuited by foreign matter in the cell. Contact INFICON.
General Questions Very low or no instrument response detected, yet compounds are known to be present The 2020ComboPRO has not been properly calibrated. Verify the concentration of the span gas. Calibrate the 2020ComboPRO. See page 60. Memory slots are not set up correctly. Program the memory slots. See page 61. Response Factor has been set to zero. Set Response Factor to 1.0 or refer to Table 6 for correct response factor. Detector is leaking. Ensure the UV lamp is correctly installed.
Erroneous high readings Date and time setting are not retained Display is blank Sample flow is less than 300 ml/min 94 Sampling environment is very humid. Water vapor may contain mineral salts which carry a charge. The water vapor becomes an electrolytic solution which becomes ionized when it enters the detector. The 2020ComboPRO is not properly calibrated. Ensure that the calibration gas is the correct concentration and calibrate the 2020ComboPRO as described on page 63.
Liquid has been aspirated. The 2020ComboPRO has been exposed to a solvent that can pass through the inlet filter. Contact INFICON. Very corrosive gases have been sampled.
