Cable Length Meter
Page 14
4.2 Pair SGL Key
The Cable Length Meter can measure single- or two-conductor wires. Press the
PAIR SGL key to toggle between single or two conductor. For single-conductor
measurement, the unit is connected at both ends of the wire/conductor. For two-
conductor measurements, the unit is connected one end of the wire and the other
end of the pair is shorted (wire length = total resistance/2).
SET LEN Key (AWG Mode Example)
The Set Length function allows the user to change factory default ohms per feet
coefficients values, based on a sample length of wire. Press the SET LEN key to tog-
gle between the AWG Mode screen (Figure 4-1) and the Set Length Mode screen
(Figure 4-2, below). In Set Length mode, the unit measures the sample wire’s resis-
tance. Press the UP/DOWN keys to adjust the wire length from 100 to 200 feet
(31.3 to 62.5 m). The smaller digits display ohms per feet, based on the sample wire.
Press and hold the SET LEN key down for a few seconds to store the new coeffi-
cients and override factory default values.
Figure 4-2. Set Length Mode screen.
Example: The factory default for 12 AWG copper is .0017 ohms/feet.
1. Using the MODE key, select AWG mode.
2. Using the UP/DOWN keys, set the AWG to 12.
