Modifying Cable Length

Although it is possible to splice additional cable to the separate sensor of the appropriate MQ model, note that the

cable wires are soldered directly into the circuit board of the meter. Care should be taken to remove the back

panel of the meter in order to access the board and splice on the additional cable, otherwise two splices would

need to be made between the meter and sensor head. See Apogee webpage for further details on how to extend

sensor cable length: (http://www.apogeeinstruments.com/how-to-make-a-weatherproof-cable-splice/).
