inserting the plug end of the test lead into the mA uA
input. The beeper emits an Input Alert if the fuses are
good.
Although this procedure will allow you to get started
quickly, we suggest that you take the time to read the
remainder of this manual so that you can learn to take full
advantage of your meter's capabilities.

How to Use the Meter

This section describes your meter and how to use it. For
ease of reference, each description is numbered and
keyed to the illustration inside the front cover.

Input Terminals and Input Alert

Items 1-4 describe the input terminals. (See Table 1 for
overload limits.) If the test leads are connected to the
Amperes input terminal, and the function selector switch is
not in the Amp measurement position, the beeper will emit
an Input Alert. An Input Alert will also sound if the test
leads are connected to the mA uA terminal and the
function switch is not in either Amp position. After an Input
Alert sounds, the meter will attempt to take a reading from
inputs applied to the T terminal. Input Alert can be
disabled by pressing T while turning the rotary
switch from OFF to any function position.

Function Selector Rotary Switch
Item 5 describes functions that are selected by setting
the rotary switch. Each time the rotary switch is
moved from OFF to a function setting, all LCD
segments will turn on for one second as part of a
selftest routine. (This selftest routine is also
performed if the rotary switch is turned slowly from
one position to another.) The meter is then ready for
normal operations and will respond to the rotary
switch and pushbuttons.
