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).
