Models 110, 111 & 112 
True RMS Multimeters
The Fluke Model 110, Model 111, and Model 112 are battery-
powered, true-RMS multimeters (hereafter "the Meter") with a 
6000-count display and a bar graph. This manual applies to all 
three models. All figures show the Model 112.  
The Meter measures or tests the following: 
•  AC / DC voltage and current 
• Resistance 
• Continuity 
• Diodes  
•  Voltage and current frequency 
• Capacitance 
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.

"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  
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 
WWarning 
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, 
LEAd
 is displayed briefly when you move the rotary 
switch to
 or from any A position.
