Combustion Analyzers

Either the sensor is installed incorrectly, or the sensor is expired and needs replaced.

The CO2 reading is a calculated number based on the fuel selected in the analyzer setup and the O2 reading. Typically, the CO2 appears stuck when the O2 sensor needs replaced and the O2 reading is always at 0.0%.

No. Each time you power up the instrument, it goes through a 60 second warm-up countdown. At the end of that countdown, the analyzer sets the O2 reading at 20.9% (ambient air O2 content) and the CO at 0 ppm, effectively calibrating the O2 channel.

Enter into the main menu, then the diagnostics menu, and finally select the O2 Sensor Life option. Depress the F3 key to reset the date code. Enter the O2 date code from the new sensor and depress the center key. Verify the month and year are correct, then depress the center key again. Return to the main menu and begin testing. See section 5.4.3 of the user manual for further specification.

Depending on which model you have, it can be either 6 months or 1 year. PCA, PCA2, Fyrite Tech60, Fyrite Pro and ECA450 have a 6 month calibration interval. Fyrite InTech, Fyrite Insight, Fyrite Insight Plus, PCA3 and PCA 400 have a 1 year calibration interval.

The B-Smart CO sensors are standard CO sensors that are run through multiple gas level tests and are given a B-Smart code based on the sensor output. Once installed in an analyzer, this B-Smart code is entered into the analyzer, which tells the instrument how to interpret the sensor output, and what to display on the analyzer screen. See section 5.4.5 of the user manual for further specification.

This is an indication that the thermocouple is not connected to the correct input, is bad, or the wires inside the thermocouple male connector on the probe assembly are broken or disconnected. See section 6.1 of the user manual for further specification.

These are all calculated values that require all inputs be present and that the O2 reading is less than 16%. If the O2 reading is 16% or higher, the programming of the analyzer will only show dashes, thus indicating an extremely poor combustion process, or no valid combustion process is occuring. This can also occur if there is a leak or obstruction in the probe assembly, or an inoperable sample pump. See section 6.1 of the user manual for further specification.

Make sure the analyzer is in the RUN mode and the pump is running. Check that the T-Stack is indicating a temperature, and that the O2 level is below 16%. If the O2 level is 16% or higher, check the device you are testing to make sure it is actually exhausting gasses lower than 16%. Check the probe for leaks or obstructions, and check the pump for proper vacuum or pull.

Multi-Zone

Please see our technical bulletin HGM-MZ Sample Pump Flow and Manifold Testing for information on resolving an 1800 fault. It is the first topic covered in the bulletin. See section 4.5.3 of the user manual for further specification.

Each zone of the HGM-MZ can be set for a different refrigerant in the 1st Zone Setup screen. See section 4.2 of the user manual for further specification.

Each zone of the HGM-MZ can be set for different alarm levels in the 2nd Zone Setup screen. See section 4.3 of the user manual for further specification.

You must first acknowledge all alarms, then the alarms will reset automatically once the affected zones are sampled again.

If the HGM-MZ is set for AUTO Acknowledge, the MZ will acknowledge automatically. If the HGM-MZ is set for MANUAL, it will be necessary to highlight each zone in the alarm screen and depress the left arrow to acknowledge each zone. See section 4.4.4 of the user manual for further specification.

All faults will reset automatically once the fault condition is corrected.

Setting the sample tube length is required so the HGM-MZ samples each zone for the correct amount of time to pull the sample into the HGM-MZ for proper analysis. See section 4.2.3 of the user manual for further specification.

Annually replace the hydrophobic filter inside the case and the external charcoal purge filter. Sample tube line end filters should be cleaned or replaced annually as well. See section 5.1 of the user manual for further specification.

Ideally, the purge line should be routed outside the building to an area that is free of all contaminates. If this is not possible, the purge line should be routed outside of any area where there might be refrigerant. The charcoal purge filter should be used in all instances. See section 2.2.3 of the user manual for further specification.

You can use a line end water stop P/N 3015-5512 or an in-line water trap P/N 0007-1655 on each line that presents a moisture issue. See section 2.2.7 of the user manual for further specification.

You must purchase and install a 4/20 ma dual channel output PC card P/N 3015-5512. See section 2.9 of the user manual for further specification.

H-10 PRO

  1. Remove the two Phillips head screws that are located inside the probe storage area.
    CAUTION: DO NOT loosen or remove the two screws located on the back slotted area of the chassis.
  2. Disconnect the battery and remove the chassis from the case, invert it, and lay it on the workspace.
  3. Remove the four Torx screws from the bottom of the pump using a T6 Torx driver.
  4. Disassemble the two plates and rubber valve plate from the pump.
  5. Remove the rubber valve plate and clean with a clean, dry cotton swab and a can of keyboard duster.
    CAUTION: When using the keyboard duster, make sure you hold the rubber valve plate to avoid blowing it from the bench top.
  6. Re-assemble in reverse order and check pump for proper operation.
