DEATH ON CONTACT may result if 1.003 DISP personnel fail to observe safety precautions. 1.004 DISP Ambient temperature: 21C - 25C. 1.004 DISP Relative humidity: less than 80%. 1.004 DISP Allow the UUT 30 min. to stabilize. 1.005 HEAD CALIBRATION ACCESS PROCEDURE 1.006 DISP Disconnect the test leads and the battery eliminator 1.006 DISP if attached. Open the battery compartment, and 1.006 DISP disconnect the battery. Remove the three phillips-head 1.006 DISP screws from the bottom of the case. Turn the instrument 1.006 DISP face-up, and grasp the top cover at both sides of the 1.006 DISP input connectors. Then, pull the top cover from the UUT. 1.007 DISP NOTE: The top AC shield should remain installed on the 1.007 DISP instrument while the calibration adjustments are being 1.007 DISP performed. The positions of the trimpots and trimcaps 1.007 DISP are marked on the top AC shield along with a table 1.007 DISP summarizing the calibration procedures. 1.008 DISP The performance of the 8060A AC functions is affected 1.008 DISP by the capacitance between the main PCB and the bottom 1.008 DISP AC shield, which is dependent on the distance between 1.008 DISP them. The distance may vary, depending on whether the 1.008 DISP top cover is installed. To minimize performance 1.008 DISP variations, press down on the AC shield to simulate top 1.008 DISP cover installation while you perform the AC calibration. 1.009 DISP Re-connect the battery to the UUT battery jacks and 1.009 DISP turn the UUT power switch on. 1.010 HEAD DC VOLTAGE ADJUSTMENT 1.011 DISP Connect the 5700A and the UUT as follows. 1.011 DISP [32] 5700A OUTPUT HI to UUT V Ohm S 1.011 DISP [32] 5700A OUTPUT LO to UUT COMMON 1.012 RNG 2V 1.013 DISP Turn R6 fully clockwise (CW). 1.013 DISP Turn R5 fully counterclockwise (CCW). 1.014 5700 1.9V S 2W 1.015 DISP Adj R5 (COARSE) for a reading between 1.9010 and 1.9025. 1.016 DISP Adj R6 (FINE) for a UUT reading of 1.9000+/-0.0001V. 1.017 5700 * S 1.018 RNG 200mV 1.019 5700 190mV S 2W 1.020 DISP Adjust R8 for a reading of 190.00+/-0.01mV. 1.021 5700 * S 1.022 HEAD AC VOLTAGE ADJUSTMENT 1.023 RNG 200mV AC 1.024 DISP Turn R18 fully clockwise (CW). 1.024 DISP Turn R15 fully counterclockwise (CCW). 1.025 5700 100mV 200H S 2W 1.026 DISP Adj R15 (COARSE) to read between 100.40 and 100.95. 1.027 DISP Adj R18 (FINE) to read 100.00+/-0.05mV. 1.028 5700 * S 1.029 RNG 200V AC 1.030 5700 100V 10kH S 2W 1.031 DISP Adjust C3 for a reading of 100.00+/-0.05V. 1.032 5700 * S 1.033 RNG 2V AC 1.034 5700 1V 10kH S 2W 1.035 DISP Adjust C7 for a reading of 1.0000+/-0.0015V. 1.036 5700 * S 1.037 RNG 200V AC 1.038 5700 100V 10kH S 2W 1.039 MEMI Enter UUT reading in volts: 1.040 MATH MEM1 = MEM - 100 1.041 JMPZ 1.043 0.05U 1.042 JMP 1.031 1.043 5700 * S 1.044 RNG 20V AC 1.045 5700 10V 10kH S 2W 1.046 DISP Adjust C8 for a reading of 10.000+/-0.01V. 1.047 5700 * S 1.048 HEAD FREQUENCY COUNTER ADJUSTMENT 1.049 DISP Press the HZ button under the display. 1.050 RNG 200mV AC 1.051 5700 50mV 100kH S 2W 1.052 DISP Adjust R9 for a stable reading between 99.95 and 100.05. 1.053 5700 45mV 100kH S 2W 1.054 DISP If the signal level is no longer sufficient to obtain 1.054 DISP the required reading (100.00kH), leave R9 at the most 1.054 DISP stable and accurate setting. 1.055 END
