Probe connection:
(Probe mounted without display unit)
The unit requires a DC power supply between about 12 and 24 volts, at less than 10 mA. The supply
should be free of high frequency noise - if it is derived from a switching power supply it is advisable to use
a series inductor and parallel capacitors to filter it. The unit provides a regulated 5V DC output at up to 50
mA for external use. If the display unit is used, connect the power to it.
The probe is provided with a length of cable attached. If this length is not sufficient, an additional length
may be added up to a distance of about 100ft. Make the connection in a suitable connection box. The
cable used must be a pair of shielded twisted pairs, of any gauge from about 16AWG to about 26 AWG.
