What to do if Apex Instruments Laboratory Equipment LCD screen has no power?
- J
  Julie RichAug 17, 2025
  If the main circuit breaker on the front of the Apex Instruments Laboratory Equipment console is extended, showing a red shank, push it back in. However, if this occurs repeatedly, immediately turn off the console, disconnect the power, and remove it from service until it can be inspected and repaired. Also, ensure that the console main power switch is turned on and the equipment is plugged into a working power outlet with the correct voltage output. Finally, check the connector in the bottom-right corner of the board to make sure that all wires are firmly clamped inside of the connector and that the connector is plugged into the board.

Why is the DGM volume not increasing on my Apex Instruments XD-502?

  Erin Hamilton MDAug 19, 2025
  If the DGM volume is not increasing on your Apex Instruments Laboratory Equipment, first, ensure the console is standing upright. If that doesn't solve the problem, check all fittings and tubing inside the console for leaks and repair if necessary. Finally, verify that the console scaling factor is correct and not set at 0.0000 or 1.0000. Input the correct scaling factor from the most recent full calibration into the settings through the console menu option.

What to do if Apex Instruments XD-502 pump motor fails to start or hums?
- M
  Mark WallerAug 22, 2025
  If the Apex Instruments Laboratory Equipment pump motor fails to start or hums, check for the correct current (5 to 6 Amperes) and see if the fuse is blown. If the unit has frozen due to ambient temperature, move the pump to a warmer environment to heat it up and then return it to the sampling location. Also, consider if the unit has overheated or if the console is connected to an incorrect voltage power source, such as a 120V power source.

How to adjust screen contrast on Apex Instruments XD-502?
- H
  holdendonnaAug 28, 2025
  If the screen contrast on your Apex Instruments Laboratory Equipment is too dim or bright, making it hard to read, first ensure the console is plugged into a working power outlet with the correct voltage. If the issue persists, adjust the console contrast using a Phillips head screwdriver through the access hole on the front of the faceplate just under the LCD screen. Make small turns counter-clockwise to decrease contrast or clockwise to increase contrast.

What to do if the vacuum transducer on Apex Instruments XD-502 reads non-zero?
- J
  Jeff MorganAug 31, 2025
  If the vacuum transducer on your Apex Instruments Laboratory Equipment reads a non-zero value when no flow is going through the system, recalibrate the vacuum sensor using a NIST-traceable reference vacuum gauge. Also, check the tubing connections between the inlet to the console and the vacuum gauge, and consider replacing the Main board.

Why is the probe, oven, or AUX not heating on my Apex Instruments XD-502 Laboratory Equipment?
- M
  Ms. Krystal Baker MDSep 2, 2025
  If the Probe, oven or AUX of your Apex Instruments Laboratory Equipment is not heating or receiving power, turn on the switch for the appropriate temperature controller. Ensure the power output is securely connected on the console faceplate and the umbilical cable. Also, verify that the Fuji controller settings are correct and adjusted to the correct set point.

How to fix TC values changing too quickly on Apex Instruments XD-502?
- M
  Melissa FloresSep 5, 2025
  If the TC displayed values on your Apex Instruments Laboratory Equipment are changing too quickly to read, adjust the TC damping settings in the console menu. If the value is jumping large amounts, increase the damping band. If the value jumping small amounts, increase the damping block size.

How to stabilize the H reading on Apex Instruments Laboratory Equipment?
- A
  Andrew CarlsonSep 8, 2025
  If the H reading on your Apex Instruments Laboratory Equipment is changing too quickly and is difficult to read, adjust the ?H damping settings in the console menu. If the value is jumping large amounts, increase the damping band. If the value jumping small amounts, increase the damping block size.

How to troubleshoot inaccurate TC readings on Apex Instruments XD-502 Laboratory Equipment?
- C
  Carol PittmanSep 12, 2025
  If the TCs on your Apex Instruments Laboratory Equipment are reading inaccurately, adjust the TC offset in the console menu using a calibrated temperature simulator. If the TC channels are not reading at all, make sure all TC wires are connected at the rear of the TC jacks inside the console. Also, ensure all TC wires are in good condition and are in their plugs on the umbilical and other sampling equipment.
