1-1. INTRODUCTION • Automatic polarity indication and overrange 1-2. This manual contains complete operating and maintenance instructions for the Fluke Models 8010A and 8012A Digital Multimeters. The information presented in this manual reflects both instruments except where indicated by a particular model number. The term Multimeter is used throughout this manual to indicate both the 8010A and the 8012A. 1-3. The Multimeters are portable bench-type digital multimeters (DMMs) with 3-1/2 digit liquid crystal displays (LCDs). The Multimeters have the following industry-standard features: • Voltage measurements from 100 ¡jlV to 1000V dc and 10 mV to 750V true-rms ac. • Current measurements from 100 nA to 2 A dc and 10 IjlA to 2A true-rms ac (up to 10A for the 8012A). • Resistance measurements from 100 mil (1 mil for the 8012A) to 20 Mil. The Multimeters also have the following special measurement features: • Conductance measurements up to 10,000 Mil of equivalent resistance. • Resistance ranges that supply enough voltage to turn on a PN junction for testing diodes and transistors. indication. Protection from overloads and transients up to 6 kV for 10 microseconds. Dual-slope integration a/d conversion to ensure noise-free measurements. Long term calibration stability (1 year). M. Your Multimeter is warranted for a period of one year upon shipment of the instrument to the original purchaser. Conditions of the warranty are given at the front of this manual. 1-5. OPTIONS and Accessories 1-6. The use of your Multimeter can be enhanced by the options and Accessories available for these instruments. The options and Accessories are listed in Table 1-1. The Multimeters can be ordered with the Option 8010A-01 or 8012A-01 Rechargeable Battery. Detailed information on options and Accessories is contained in Section 6 of this manual.
