5-37.Replacing the Fuses
Referring to Figure , examine or replace the Meter's fuses as follows:
1.Turn the Meter off and remove the test leads from the terminals.
2.Remove the battery door assembly by using a standardblade screwdriver to turn the battery
door screw one-half turn counterclockwise.
3.Remove the fuse by gently prying one end loose, then sliding the fuse out of its bracket.
4.Install only specified replacement fuses.
5.Reinstall the battery door assembly and secure it by turning the screw one-half turn clockwise.

True RMS
AC True RMS
The term stands for "Root-Mean-Square" which
represents the method of calculation of the voltage
or current value. Average responding multimeters
are calibrated to read correctly only on sine waves
and they will read inaccurately on non-sine wave
or distorted signals. True rms meters read
accurately on either type of signal.
