Because of a high- efficiency, quadrature-type of winding, wire size and location of the conductor within the transformer jaws do not affect the accuracy of the current measurement. The transistor tester described in the following paragraphs provides approximate test information. Ensure that power is removed and the circuits are discharged before measuring in-circuit resistances. Verify that the overrange indication 1 appears on the LCD.
I- FigureDiode Test Operation The zebra strip is located in a channel on the display mounting bracket. Learn More – opens in a new window or tab International shipping and import charges paid to Pitney Bowes Inc. Set the switch in the test fixture to BETA. Reinstall the case and relabel the ac line voltage designation on the decal at the bottom of the instrument.
The 2 kO range is preferred and is marked with a larger diode symbol on the front panel of the instrument.
This item may be a floor model or store return that has been used. Flukr crest factor capability of your Multimeter is shown by the following equation: Pull the wire up through the fuse holder slot. Learn More – opens in a new window or tab Any international shipping and import charges are paid in part to Pitney Bowes Inc.
Digital Multimeter 8012A
Adjust R7 on 801a rms hybrid network so that the voltage level on TP2 is within 0. InstaD the center mounting bracket as shown in Figure ,-4 and secure it to the mounting panel using the nuts provided. Harrisburg, Pennsylvania Allen-Bradley Co. Auburn, New York Burndy Corp. The signal conditioner circuits also provide protection from transients and overrange conditions. Dual slope integration takes advantage of the natural laws governing the charge and discharge of capacitors.
Carefully slide the front panel forward until it is clear of the switches and the LCD. Minus sign improperly displayed. An optional rechargeable battery pack is available for both Multimeters. Tel;TLX: Readings are noisy on all ranges.
The Model Y Current Transformer js a small clamp-on current transformer designed to extend the current measuring capability of your Multimeter up to I50A. The transistor tester fixture is described in Figure The theory of operation of your Multimeter is discussed on two levels. Use the following procedure to adjust the dc offset of the rms converter: Signals on the 20V range can now be measured by the mV function 0812a U3. Extended Frequency Response Useful for flkue readings from 20 kHz to MHz Response Responds to the peak value of an input and is calibrated to read rms value of a sine wave Voltage Range 0.
The method of measuring conductance is the same as for measuring resistance with one exception. Figure describes how to operate your Multimeter for diode tests. Remove the display assembly before washing the pcb and do not install it until the pcb has completely dried.
Rent Fluke A DMM 3_-Digits, 10A, 2-Ohm | Transcat
Parts price information is available from the John Fluke Mfg. The lOA Range current measurement feature of the A is described in the following paragraph. Line power input is rectified, filtered, and regulated.
The range switches determine the combination of current shunts used the measurements. Crest factors start at 1. If your Multimeter has the – 01 Battery Option, refer to Section 6 for information on changing ac line voltages.
Fuses FI and F2 protect the current shunts from overcurrent conditions. The integrate period lasts for a count of Insert the probe tips into a standard wall socket. Remove the retaining screw from the rear of the cases and separate the instruments from their cases. The mA input connector contains an in-line fuse. A count of generates an overrange pulse and the overrange indicator appears on the LCD. The discharge time is proportional to the level of the unknown input voltage.
MA Mexico, Mexico D. The LCD may now be lifted free from the display mounting bracket. Slide the spring down the wire towards the Main PCB. The Touch and Hold feature fkuke activated by a push button located on the probe. If reshipment of the instrument is necessary, please use the original shipping container.
They route or shunt the current around the meter.
