Verification Test

Programs

All test procedures should comply with the following test conditions:

•Ambient temperature of the test area is between 18°C and 28°C and stable to within ±1°C.

•Ambient relative humidity of the test area is <80%.

•Must have a one hour warm-up with all input signals removed before verification or adjustment.

•Use only copper connections to minimize thermal offset voltages.

•Use shielded twisted Teflonâ insulated cable or other high impedance, low dielectric absorption cable for all measurements to reduce high resistance errors.

•Keep cables as short as possible. Long test leads can act as an antenna causing the pick-up of ac signals and contributing to measurement error.

•Allow 5 minutes after handling input connections for thermal offset voltage settling.

Make copies of the Performance Test Record (at the end of this appendix) for use in performance verifying each channel (use one test record copy per channel). The test record provides space to enter the results of each Performance Verification test and to compare the results with the upper and lower limits for the test.

The value in the "Measurement Uncertainty" column of the test record is derived from the specifications of the source used for the test and represents the expected accuracy of the source. The value in the "Test Accuracy Ratio (TAR)" column of the test record is the ratio of digitizer accuracy to measurement uncertainty.

Performance Verification Test programs are provided so you can performance verify your digitizer. These programs were developed on a PC running Windows with a GPIB interface and SICL/Windows for GPIB software. All projects written in C programming language require the following settings, files or paths to work properly:
