FUNCTION
DC/AC/Audible tone
A push-push
switch (push on - push
Switch
off, do not pull). When using V or mA
functions,
the in position
selects
AC
measurement
functions
and
the out
position selects the DC measurement
function. When used with Q or S func-
tions, the in position enables the audi-
ble tone feature and the out position
disables the audible tone feature.

Input Overload Protection
CAUTION
Exceeding the maximum
input overload limits can damage your instrument.
The transient overload protection circuit is intended to protect against short
duration high energy pulses. The components used limit the protection to
approximately five pulses per second for 6 kV, 10microsecond
pulses, and
about 0.6 watts average for lower pulses. Fast rep rate pulses as from a TV set
can damage the protection components; RV1 - RV4, R1 and R2', if replaced,
use only Fiuke replacement parts to maintain product safety. * R2 is a fusable
resistor. Use exact replacement to insure safety.
2-14.
Each measurement function and its associated ranges are equipped with input
overload protection. The overload limits for each function and range are given in Table 2-
