Rotate the display frame forward and down until the two hooks on the bottom of the display frame release the display mounting bracket. The proper function of U3 depends on external components to establish the basic timing and analog levels.

If the multimeter burden voltage is significant, the formula in Figure can be used to calculate the burden voltage error. There is one, user-replaceable fuse FI in your Multimeter. Cl has charged to a level proportional to the level ffluke the unknown input voltage.

The functional block diagram shows that the multimeter can be divided into two general circuits, the Input Signal Conditioners and the Gluke Voltmeter. The component frequencies, for rise times less than 1 microsecond, exceed the kHz bandwidth of your Multimeter and will produce a low reading display.

Fluke 8012A Digital Multimeter

Note battery probably will need charging. This error will be proportionally higher for higher frequency square waves. Replace the handle mounting screws through the side brackets into the mounting bosses.

Before starting the Calibration procedure, perform the Calibration Access procedure given earlier in this section. Unit works on battery or AC. The Y has detachable leads and is used in conjunction with the voltage inputs of the Multimeter.

See all flukd definitions – opens in a new window or tab An item that has been used previously. This output voltage will be from mV to mV or -2V to 2V, depending on the selected range. The transistor tester fixture is described in Figure On these two ranges, if a high level input is applied for more than the 10 second maximum, R14 may be damaged and no longer provide the proper protection.

Improper decimal point indication. Watch list is full.

Your Multimeter uses the ratio method to measure an unknown resistance. Mathematically, rms is defined as the square root of the mean of the squares of the flike voltages.

The overrange pulse will also cause the digital controller to restart the auto-zero period. The appropriate measurement function of U3 is enabled by the range switches too. Use the following procedure to verify the proper 801a and accuracy of the AC Voltage function: Disconnect the power cord from rear of flyke instrument. Part Number and Revision Level of components pcb. Gently pry upwards until a few turns of the spring are free 801a the fuse holder.


A A Figure Your Multimeter is a true-rms-responding multimeter, and the display may indicate a reading of 1 to 2 digits because of amplifier noise when the input is shorted in the AC V or AC mA functions. Figurepart D shows the mA input line free of the fuse holder.

Measure the voltage level on TP2. Turn the instrument upside down. If flluke original container is not available, be sure that adequate protection is provided to prevent damage during shipment.

Additional operating instructions and applications are given in the paragraphs on Applications, later in this section.

Please enter a number less than or equal to 1. Fuse F2 is rated for 8102a at V. Y our Multimeter can measure signals with a crest factor of 3.
