Model 1101-B
Compact Digital Multimeter
Instruction Manual
1. Introduction
The
Triplett Model 1101-B
is a 3 1/2 digit, handheld Digital Multimeter with Auto Power Off and
a backlit LCD display. At its core is an LSI (Large Scale Integration) integrated circuit that uses
dual slope A/D conversion for stability and accuracy. The meter can measure AC and DC Voltage
and DC Current, Resistance, Temperature, Transistor gain, and perform a Diode and Continuity
Test. Overload protection makes the meter resistant to damage from accidental overloads.
2. Panel Layout
1)
LCD Display with
(Low Battery) and
H
(Hold) annunciators
2)
Data-Hold Button (HOLD). Press to ‘freeze’ the present LCD reading. Press again to ‘un-
freeze’ the reading.
3)
Back Light Button / Auto Power Off Reactivate: Press to turn on the LCD backlight. The
backlght will turn itself off automatically in a few minutes. If the meter turns itself off after
approximately 30 minutes (Auto Power Off feature activates), press this button to reactivate the
meter, or set the Rotary Switch to OFF and then to the desired range.
4)
Rotary Switch: Use this switch to select functions and ranges
5)
Input Jacks: Plug in test leads for the desired measurement type.
