DTS-2077 Calibration Procedure
(17 April, 1998
)
3
(2-5) Using the voltmeter, measure the (+OUT) output of the +5VDC power supply (re d
wire)
at TP5 on the backplane referenced to ground. Verify the voltage is +5VDC +0.05V. If
necessary, adjust the main supply adjustment.
(2-6) Using the voltmeter, measure -5VDC on Pin 3 of the power connector (P2) on the MSU
board (large board on bottom of DTS) as shown in Figure 1B. Verify the voltage is -
5VDC
±
0.05V. If adjustment is required, both -5VDC modules must be alternately
adjusted at VOUT. The two -5VDC modules provide load sharing, and must be balanced
to provide optimum performance.
Reference Voltage Check
(2-7) 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.
