Operating Procedure - Textron Greenlee CM-660 Manuel D'instructions

AC Bandwidth
AC bandwidth is the range of frequencies over which AC measurements can be made
within the specified accuracy. It is the frequency response of the AC functions—not
of the frequency measurement functions. A meter cannot accurately measure the AC
value with frequency spectrums outside its bandwidth. Complex waveforms, noise,
and distorted waveforms contain frequency components that are much higher than the
fundamental; for example, high frequency noise on a 50/60 Hz power line.
Operation

Operating Procedure

1. Refer to the "Settings Table." Set the selector to the proper setting, press SELECT
(when instructed to do so), and connect the test leads to the meter.
2. Refer to "Typical Measurements" for specific measurement instructions.
3. Test the unit on a known functioning circuit or component.
• If the unit does not function as expected on a known functioning circuit, replace
the batteries.
• If the unit still does not function as expected, call Greenlee for technical assis-
tance at 800-435-0786.
4. Take the reading from the circuit or component to be tested.
