The DCμA funcon is designed especially for HVAC ame sensor applicaons. The 0.1μA resoluon is useful for identifying the very small current changes in ame detector applicaons. Flame signal current check should indicate steady ame signal of at least 2μA for a reccaon type, or 1.5μA for an ultraviolet type (8μA for self-checking systems). For ame signal currents with inadequate strength or with uctuaons beyond 10%, check the following to avoid the risk of unwanted ame relay dropout:

For gas or oil ames (UV):

• Low supply voltage
• Detector locaon
  • Defective detector wiring
• Dirty viewing windows

For oil ames (Photocell):

• Detector locaon & wiring
• Smoky ame or poorly adjusted air shuer
• Faulty Photocell
  • Temperature > 165 °F (74 °C) at photocell

For gas ames (Flame Rod):

- Ignion interference (A ame signal current dience with the ignition both on and o greater than 0.5μA indicates the presence of ignition interference)

- Insucient ground (must be at least 4 mes the detector area)

- Flame liing o burner head (ground), or not connuously in contact with the ame rod

- Temperature > 600 °F (316 °C) at the ame electrode insulator causing short to ground.

6. Maintenance

WARNING!

To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input jacks and turn OFF the meter before opening the meter's housing. Do not operate with an open housing.

6.1 Troubleshoong Tips

If the instrument fails to operate, check the baeries and the test leads, and replace as necessary. Double check the procedures outlined in this manual.

If the instrument's positive input terminal has been subjected to a high voltage transient (caused by lightning or a switching surge to the system under test), the impedance of the protective components in series might be compromised (creang a high impedance) and will act like an open fuse. Most measuring funcons through this terminal might then be subject to an open circuit. Such components should only be replaced by a qualified technician.

6.2 Accuracy and Calibraon

Accuracy is specified for a period of one year aer calibraon. Periodic calibraon at intervals of one year is recommended to maintain meter accuracy.

6.3 Cleaning and Storage

Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for more than 60 days, remove the baeries and store them separately.

6.4 Baery Replacement

To avoid electrical shock, disconnect the meter if connected to a circuit, remove the probe leads from the terminals, and set the funcon switch to the OFF posion before aempng to replace the baeries.

The rear baery compartment locking screw has a LOCK and UNLOCK posion.

Replace the two (2) standard 1.5V AAA baeries, observing correct polarity.
