DTS-2070C Calibration Procedure
(17 April 1998)
3
(2-6)
Using the voltmeter, measure -5VDC at TP3 of the back plane. Verify the voltage is
-5VDC
±
0.05V. If adjustment is required, the -5VDC module closest to the DTS front
panel must be adjusted at VOUT.
(2-7)
Using the voltmeter, measure -5VDC at the location shown in Figure 1B on the TMU470
board. Verify the voltage is -5VDC +0.05V. If adjustment is required, the -5VDC
module closest to the DTS center bulkhead must be adjusted at VOUT.
(2-8)
Using the voltmeter, measure -2VDC at TP4 of the back plane. Verify the voltage is
-2VDC +0.02V.
Reference Voltage Check
(2-9)
Using the digital voltmeter, probe the red and black pin jacks located on the back panel of
the DTS, verify the DC voltage reads within
±
1.1m VDC of the value recorded on the
previous calibration label. Record this value in the test data record.
