meter at least four inches for each reading. Take the average of the readings.
The built-in average function is ideal for this task.
Do not use the CTM to measure tension for wires if both of the following are
true:
1. No wire calibrations are stored of the same diameter as the wire you are

ity. Dramatic temperature changes (such as moving from a warm vehicle to
cooler outdoors) requires time for the sensor to reach the same temperature.
Direct sunlight will heat the electronics cavity and cause higher readings
than actual ambient temperature. In these cases, use a seperate thermom-
eter to determine temperature. Be certain to enter this temperature into the
CTM if using the quick-tensioning mode with the temperature dependent
acceptance window.
For best tension accuracy, use the exact temperature of the wire. This may
be widely different from the ambient temperature if the cable has been sitting
in direct sunlight.
