Maintenance and Troubleshooting Information
Troubleshooting the Instrument
The advanced design of the DP-IR makes it one of the most reliable leak survey instruments
available. However, should you experience problems with the instrument or suspect that the
instrument is not operating properly, do not use the instrument for leak survey work until the
problem is resolved.
Only a qualified DP-IR repair technician should attempt to repair or open the instrument. There
are no user-serviceable components in the DP-IR that can be repaired or replaced other than the
battery.
