C. INSTALLING THE BAROMETRIC PRESSURE SENSOR
The barometric pressure sensor is located inside the console; no user installation is
required. The sensor does need to be calibrated, however. Allow a one-hour warm-
up period before carrying out the barometric pressure calibration steps listed in
Section 5: Calibration.
D. INSTALLING THE TEMPERATURE SENSORS
The temperature sensor is wound into 25 ft. coils.
If the temperature cable provided is not long enough, it may be extended by splicing
on the extra length of 22 gauge, stranded, 2 conductor shielded cable with a ground
drain wire. When cutting and splicing, insure good contacts, proper color coding of
the terminal leads, and a good seal. (A good solder splice and waterproof insulation
are essential; merely twisting the respective wires together is not adequate.) Addi-
tional cable (Cat. No. 81560) and a water tight splice kit (Cat. No. 81580) are avail-
able from the factory. The maximum length of the cable (original cable plus spliced
section) should not exceed approximately 1500 ft. (457 m).
