Information

The Model 8040A Multimeter provides the accuracy and portability required in today’s field service work. A slide-out sunshade protects the 4/2 digit LED display from glare when operating the 8040A in adverse lighting conditions. The small size and battery power add to the portability; yet the fold-away stand allows the instrument to be positioned at a convenient angle for bench top use. The 8040A offers 20,000 count resolution in all five functions which provides measurement resolution to 0.01 ohms on the 200 ohm range and 10 microvolts on the 200 millivolt range. AC voltage and current measurements are made using true rms conversion techniques for improved accuracy in communications and industrial control applications. Several Accessories are available for use with the 8040A to expand its’ capabilities. A list of these Accessories is provided in Table l-1 while more detail about each one is provided in Section 6. Note that two of the Accessories, the 80T-150 temperature Probe and A8l battery charger/eliminator, are configured at the factory for particular applications. Insure that the correct form of the model number is used when ordering either of these Accessories.
