1: INTRODUCTION
The Triplett Model 1101-A is a 3 1/2 digit, handheld Digital Multimeter with a
backlit LCD display. At its core is an LSI (Large Scale Integr ation) integrated
circuit which uses dual slope A/D conversion for stability and accuracy. The meter
can measure AC and DC Voltage and Current, Resistance, Temperature, Transistor
gain, and perform a Diode and Continuity Tes t. Overload protection makes the
meter resistant to damage from accidental overloads.

7.3.5 If the displayed value is less than "200" (decimal po int not shown), a
more accurate reading may be obtained by setting the RANGE switch
to a lower range. Remove power from the circuit, disconnect the test
probes, and rotate the RANGE switch to the next lower posit ion (and,
if necessary, move the red test lead from the 10A jack to the V/Ω /mA

voltage on the LCD display. If the RANGE switch is already on the
lowest position (i.e. 2000 uA), no greater measurement resolution can
be obtained.
7.4 Resistance Measurement:
WARNING!
Do not apply voltage or current to the meter when it is set
to any of the Ohms Ω ranges!
7.4.1 Connect the black test lead to the COM jack, and the red test lead to
the V/Ω /mA / F jack.
7.4.2 Set the RANGE switch to the Ω posit ion that is appropriate for the
device or circuit to be measured. The LCD display will indicate
overrange (i.e. "1 - - -").
7.4.3 Connect the test leads to the device or circuit being measured.
Observe correct polarity if appropriate.
7.4.4 If the display indicates overrange, i.e. "1- - -", rotate the RANGE
switch to the next higher position and observe the reading on the LCD
display. If the RANGE switch is already at the highest po sition (i.e.
20M Ohms), the resistance exceeds the value measurable by the
meter.
7.4.5 If the displayed value is less than "200" (decimal po int not shown), a
more accurate reading may be obtained by setting the RANGE switch
to a lower range. Rotate the RANGE switch to the next lower
position and observe the reading on the LCD display. If the RANGE
switch is already on the lowest position (i.e. 200 Ohms), no greater
measurement resolution can be obtained.
Note: On the 20Ω range. The displayed value must be less than "20" to obtain
a reading on a lower range.

Notes:
1) The Transistor Gain Test does not indicate if a transistor is "good" or "bad".
It only tests for gain assuming that the transistor is good.
2) For safety purposes, the contacts in the test socket are recessed down into the
socket. This may cause difficulty when attempting to measure the gain of
transistors removed from a circuit board. To test transistors with short leads,

8.1 Backlight:
8.2 Hold:
8: BACKLIGHT AND HOLD
The 1101-A incorporates a light green LED backlight into the LCD
assembly. Since the backlight uses more power than anything else in
the meter, an anti-tease function on the button prevents accidental
turn-on, and a 20 second tim e -out prevents extended battery drain.
To turn on backlight, press and hold the Backlight / Hold button for
about 3 seconds, until the backlight comes on. Release the button. The
backlight will stay on for about 20 seconds and then turn itself off.
A Hold feature is incorporated i nto the 1101-A. It is a momentary
Hold feature that only holds a reading as long as the associated button
is kept depressed. Since the button that perform s Hold is al so the
Backlight button, if the Hold feature is engaged for longer than 3
seconds, the Backlight will turn on.
To activate the Hold feature, press and hold the Backlight / Hold
button. The Hold annunciator will appear in the LCD display for as
long as the button is held depressed.
