Repairing a Fluke 8810A Multimeter
Instructions for making ac voltage measurements are included in Section 2 of this manual. Installing the Lockout Strip OA This signal is inverted by U 1 and applied to U However, certain consider- ations are necessary to properly interface the DOU 88110a the external recorder.
Box 3t BUC. This allows the input to U3 to be changed from the dc voltage representing the unknowm input to the appropriate reference input without affect- ing the charge stored on C9.
Repeat steps 22 through 25 of this procedure. Assembly Name Fluke Part No.
flukr NOTE Do not perform this procedure as part of the normal calibration routine. Test equipment recom- mended for performance test, calibration adjustments and troubleshooting is listed in Table Refer to the rear panel decal and set the line voltage switch to the local line voltage or V ac.

Once installed in the A, the DOU re- quires no operator attention. Increase the input voltage to It offers convenient operation plus optimum accuracy and resolution when frequent range changes are required. Fuquay-Varian, North Carolina Penacook.
California Replaced by Motorola Inc. The display should read within the first display limits listed in Table Equipment required is listed in Table Kenilworth, New Jersey Monsanto, Co. This includes a list of replace- able parts and a schematic. The line power cord is a three-prong, polariz- ed connector which permits the 88 10A to be connected to line power. Autorange can also be manually selected as a range.
From Canada and other countries phone Harrisburg, Pennsylvania Ailen-Bradley Co. It contributes six ranges2 kO, 20 kO, kO, kO, and 20 MOand employs a constant current conversion technique 8810x provide a voltage reading equivalent to the measured resistance. The readout is 8810q updated and includes decimal point, polarity Vdc only and a mV dc range annunciator 20 M O and D annunciators are also included for use with the Ohms Converter Option.
Adjust the 1 kO cal R13 for an A dis- play of 1.
Under ideal interface condi- tions these lines are used to establish a handshaking arrangement between the DOU and the external recorder see Figure Adjustment names given in this procedure agree with those silk- screened onto the top guard cover. Guelph, Ontario, Canada Presin Co.
The decimal point moves around, and the variable resistor which is used to calibrate does nothing. If the voltage continues to rise, Q2 will also be connected in the series and the total standoff will then be 1 kV. The range adjustment procedure ensures the ac measurement accuracy of each available range. Rack Mount Installation Figure DC Voltage inputs applied to the instrument are conditioned by the VDC Buffer so that an input within any dc voltage range chosen produces a buffer output of 2 volts dc or less.
Also, an unusually high input impedance MO minimizes circuit loading, and thereby contributes to measurement accuracy.
Chicago, Illinois Centrelab Electronics Div. The unit should remain in the range. This section of the manual contains informa- tion concerning maintenance and servicing of the Model A Digital Multimeter.
Apartado dc Correos 48 Alcorcon Madrid. Block diagrams and simplified circuit diagrams are included to supplement the text. The connector pin assignments for each significant digit of the display are provided in Table It contributes four ac voltage ranges 2, 20,and V ac and employs a true rms conversion technique to provide true rms measurements with a maximum sensitivity of 10 ;uV.
The rate of discharge is determined by the value of the reference voltage.
