® Models 110, 111 112 Multimeters Calibration Information 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 Warning 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 symbol is displayed when the Meter detects a voltage ≥ 30 V or a voltage overload (OL) condition. Test Lead Alert Warning 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, is displayed briefly when you 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. C
