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.
