PERFORMANCE TESTS

The following paragraphs provide test procedures for verify- ing the power supply's compliance with the specifications of Table 1. Please refer to adjustment and calibration or trouble- shooting procedure if you observe any out of specification performance.

Measurement Techniques

Setup for All Tests. Measure the output voltage directly at the +S and -S terminals on the rear panel; in this way the monitoring device sees the same performance as the feedback amplifier within the power supply. Failure to connect the monitoring device to the proper points shown in Figure A-3 will result in the mea- surement not of the power supply characteristics, but of the power supply plus the resistance of the leads between its output terminals and the point of connection.

Use separate leads to all measuring devices to avoid the sub- tle mutual coupling effects that may occur between measur- ing devices unless all are returned to the low impedance terminals of the power supply. Twisted pairs or shielded cable should be used to avoid pickup on the measuring leads.

Electronic Load. The test and calibration procedures use an electronic load to test the supply quickly and accurately. An electronic load is considerably easier to use than load resis- tor. It eliminates the need for connecting resistors or rheostats in parallel to handle the power, it is much more stable than carbon-pile load, and it makes easy work of switching between load conditions as is required for the load regulation and load transient response tests.

Current Monitoring Resistor Rs. To eliminate output-current measurement error caused by voltage drops in the leads and connections, connect the current monitoring (sampling) resis- tor between -OUT and the load as a four-terminal device. Fig- ure A-3 shows correct connections. Connect the current monitoring test leads inside the load lead connections directly at the monitoring resistor element. Select a resistor with sta- ble characteristics and lower temperature coefficient (see Table A-1).
