1. Necessary for Model 7751/7753 only.
2. Characterize all resistors using ohms function of DMM
before use. All resistors are 1% tolerance, 0.5W.
3. Temperature coefficient <20ppm/°C required.
4. Voltage rating of at least 1000V required.
Characterize test resistors using ohms function of either DMM listed in
Table 16-14 before use.
Maximum common-mode voltage (voltage between any terminal and
chassis) is 42V peak.
Hazardous voltages may be present on terminals of test equipment and
test resistors. Use standard safety practices to avoid personal injury
due to electrical shock.
