10 Quick Reference Guide
Programming examples
Voltage measurement example — Table 4 shows a typical command sequence to
measure voltage on channel 1 using auto range.
Temperature measurement example — Table 5 shows a typical command sequence to
measure temperature on channel 1 using a simulated junction with 0°C reference
temperature and a type J thermocouple.
Settings to optimize performance
Range
To achieve the best accuracy, the Model 2182 should be on the lowest possible
measurement range. In most situations, auto range can be used to automatically select the
best range. Auto range is controlled (enabled/disabled) by the AUTO range key (AUTO
annunciator indicates auto range is enabled).
