Introduction
The Fluke Model 110, Model 111, and Model 112 True RMS multimeters (hereafter "the Meter") are
battery-powered, with a 6000-count display and a bar graph.
This calibration information applies to all three models. All figures show the Model 112.
The Meter measures or tests the following:
AC and DC voltage
Resistance
Continuity
Diodes
Frequency
Capacitance
AC and DC current (Model 111 and Model 112)
"Warning" and "Caution" Statements
A "WWarning" statement identifies hazardous conditions and actions that could cause bodily harm or
death.
A "Caution" statement identifies conditions and actions that could damage the Meter or the equipment
under test.
Unsafe Voltage Symbol
To alert you to the presence of a potentially hazardous voltage, the Y symbol is displayed when the Meter
detects a voltage
30 V or a voltage overload (OL) condition.
Test Lead Alert
Personal injury or damage to the Meter can occur if you attempt to make a
measurement with a lead in an incorrect terminal.
To remind you to check that the test leads are in the correct terminals,
move the rotary switch to or from any A position.
These Meters meet CAT III IEC 61010-1-95 standards. The IEC 61010-1-95 safety standard defines four
overvoltage categories (CAT I to IV) based on the magnitude of danger from transient impulses. CAT III
meters are designed to protect against transients in fixed-equipment installations at the distribution level.
