My Instrument is no longer displaying a temperature just four dashes [- – – -]

My Instrument is no longer displaying a temperature just four dashes [- – – -]

If your Instrument is displaying a series of four dashes [- – – -] across the LCD screen, instead of a temperature reading, it is usually an indication that the probe, that should be plugged into the top of the instrument, may be faulty.

Initially you should ensure that the probe is seated correctly and, if possible, try an alternate probe to see if that can produce a temperature reading.

If the issue persists and you do not have an alternate probe to try, you may want to order a replacement probe.  In most cases, the part number of the probe should be written on a small plastic label wrapped around the probe lead itself near to the probe plug end.

My Instrument reads OPEN (plus BAT in top of LCD)

My Instrument reads OPEN (plus BAT in top of LCD)

Comark ‘C’ series instruments incorporate a switch in the battery compartment to ensure that the Thermometer cannot be used if the integrity of the case is compromised and therefore ingress of liquid is possible,  that could lead to damage to the battery compartment or instrument.

Therefore if the Instrument reads OPEN on the Display and BAT is indicated, please ensure the battery compartment door is properly closed, by checking the following:

  • Check location of battery cover in slots in lower part of case; check they are not damaged or missing.
  • Check tightness of the screw in the battery compartment. Do not over tighten.

If OPEN message does not clear, please return for Service.

My Instrument reads ambient all the time

My Instrument reads ambient all the time

Comark uses the Lumberg connector on many products due to its ruggedness and ability to perform multiple connecting duties. However, this can lead to some confusion, for example, when a Thermocouple Probe, with a Brown or Green lead, is plugged into an instrument designed to accept only a Thermistor/PST probe (for example C20, or C21C).

Doing this will cause no harm to the instrument, or the probe, but the probe will not work correctly and the display may well simply show Ambient Temperature reading.

To confirm if this probe is working correctly please try this probe in a C22 or N9094.

If you believe that the probe has been ordered in error please return the probe so we can arrange an exchange.

This may cause your device to cease functioning, or become dangerous. In all cases, please return your instrument to Comark for servicing.

Ideally, prevention is better than cure for this problem. Check your batteries regularly to ensure they have not leaked, and if you are planning to store the instrument without use for a prolonged period, please consider removing the batteries and storing them separately.
