Green indicates the battery is fully charged and ready for use. It is normal for a fully charged battery to indicate it is charging (red light) when first plugged in.
Page 36: Overview
2020 Software Manual Charging a fully discharged battery pack will take approximately 4 hours. Optionally you can use the off line charger (Part No. MX350015) to charge the battery pack independently of the instrument. See Off Line Charger on page 110. If you are charging the battery pack in the instrument you can use all the features of 2020 while the battery pack is being charged.
Page 37 Introduction 2020 has many datalogging options. You can select an averaging interval, or you can use manual operation. If you select an averaging interval, the minimum, maximum, and average concentrations measured in each period are automatically recorded in 2020’s datalogging memory. 2020 can log up to 1000 entries. In manual operation, 2020 prompts you to locate a site and then to record a background and sample readings for the site.

Page 120 2020 Software Manual Hot gases and vapors may contribute to a decrease in sensitivity because they may condense on the lamp window. Condensation may 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.
Page 121 Routine Maintenance 2. Allow the lamp to cool to room temperature to avoid thermal shock which could crack the window. 3. Dampen a cotton swab in methanol and dab it into the cleaning compound. Allow a small amount of the cleaning compound to adhere to the cotton tip.

Page 129: General Information
Troubleshooting General Information If you have a service related question about 2020, consult this manual first. If you cannot find the answer in this documentation, contact the Service Department. When you call, you should have your 2020 in front of you. You should also have this manual at hand.
Page 130 2020 Software Manual Cause: Contamination of sample line, sample probe, inlet filter or fittings before the detector. Action: Clean or replace the sample line, sample probe or the inlet filter. See Replacing the Sample Inlet Filter on page 120. Cause: Span gas and zero air are mixed up. Action: Ensure clean air is used to zero 2020.
Page 131 Troubleshooting Do not remove or replace the UV lamp in a hazardous location. WARNING Action: Install a new UV lamp. See Removing and Replacing the UV Lamp on page 116. Cause: Incompatible application. Action: The concentration and sample gas are incompatible for use with 2020.
Page 132 2020 Software Manual approximately 90º and then try to start 2020 again. If the fault persists, replace the lamp. Cause: UV lamp is not installed. Do not remove or replace the UV lamp in a hazardous location. WARNING Action: Install a UV lamp. See Removing and Replacing the UV Lamp on page 116.
Page 133 Troubleshooting Action: Check for an obstruction in the sample line. Make sure the sample line, the sample probe and the inlet filter are not blocked. Do not replace the inlet filter in a hazardous location. WARNING Action: Replace the inlet filter. See Replacing the Sample Inlet Filter on page 120.
Page 134: Troubleshooting
2020 Software Manual Troubleshooting Problem: Very low or no instrument response detected, yet compounds are known to be present. Cause: 2020 has not been calibrated properly. Action: Ensure the calibration gas is of a reliable concentration and then calibrate the instrument as outlined in Chapter 3.
Page 135 Troubleshooting Action: Enter the correct response factor. Refer to page 169 for a list of response factors. If the compound is not listed or you are measuring gas mixtures, then enter a value of 1.0. Cause: You are not using the correct Cal Memory. Action: Select the correct Cal Memory for your application.
Page 136 2020 Software Manual Do not remove or replace the UV lamp in a hazardous location. WARNING Action: If you have a UV lamp with a white serial number label, it is possible that the lamp is too long for the lampholder. Replace the lamp and contact the Service Department.
Page 137 Troubleshooting Do not remove or replace the UV lamp in a hazardous location. WARNING Action: Install a new UV lamp. See Removing and Replacing the UV Lamp on page 116. Cause: High concentration of non-ionizable compounds. Action: Chemical compounds, such as methane, with ionization potentials greater than the 10.6 eV scatter and absorb the UV light.
Page 138 2020 Software Manual Action: Ensure the calibration gas is of a reliable concentration and then calibrate the instrument as outlined in Chapter 3. After the instrument has been calibrated, sample the bag of calibration gas. A reading equivalent to the calibration gas should be displayed.
Page 139 Troubleshooting Action: Do not touch the wire grid inside the detector cell. Use a gentle jet of compressed air to remove any dust or dirt in the detector cell. Do not insert any object, other than the UV lamp, into the lampholder. WARNING Cause: There is an undetermined problem.
Page 140 2020 Software Manual Do not remove or recharge the battery pack in a hazardous location. WARNING Action: Connect 2020 to the AC adapter and turn 2020 on. Turn the pump off. See Pump on page 51. While 2020 is running the internal battery is charging.
Page 141 Troubleshooting Action: Do not touch the wire grid inside the detector cell. Use a gentle jet of compressed air to remove any dust or dirt in the detector cell. Do not insert any object, other than the UV lamp, into the lampholder. WARNING Cause: There is an undetermined problem.
Page 142 2020 Software Manual Pack on page 30. You must leave the instrument on while you disconnect the battery pack. This will reset the instrument. Reconnect the battery pack and close the battery hatch. Turn on 2020, set the time and date and program all the calibration memories that you are using.
Page 143 Troubleshooting See Removing and Replacing the UV Lamp on page 116. Cause: UV lamp is too wide, causing flow to be restricted. Action: If you have a UV lamp with a white serial number label, it is possible that the lamp is too wide for the lampholder.
Page 144: Printer Troubleshooting
2020 Software Manual Printer Troubleshooting NOTE: 2020 is not classified for use in hazardous locations with a printer. Problem: Printer will not print. Cause: Printer is not connected properly. Action: Ensure that you have the correct cable for your instrument. The printer cable must be properly connected.
Page 145: Figure 25 Printer Cable Configuration
Troubleshooting information to a computer store where a suitable adapter may be obtained. Figure 25 Printer Cable Configuration Cause: Printer is not configured properly. Action: Many printers have a set of configuration (DIP) switches. Generally, these instruments expect these switches to be set in the factory default settings.
Page 146: Serial To Parallel Converter Troubleshooting
2020 Software Manual Serial to Parallel Converter Troubleshooting Problem: Data are printed correctly at first but become garbled. Cause: Baud rate may be set too high. Action: Ensure the baud rate of the printer and the serial to parallel converter are set to 9600 baud.
Page 147 Troubleshooting Cause: Cables are not configured correctly. Action: You must use the correct type of cable to ensure trouble free data transmission. The length of the cable at the parallel side must not exceed 15 feet. On the serial side, use only the 2020 printer cable and suitable adapter.
