through both a known resistance and the sensed resistance. The resulting voltages are measured and appropriate conversions are applied to the measurement, yielding a displayed output in ohms.

Frequency is measured by counting cycles for a known time period. The measurement represents the frequency observed during the sampling time. The instrument can measure a wide range of frequency inputs. Test applications might include measuring line voltage sine wave signals or measuring the output of a voltage-to-frequency converter used in a servo system.

Thermocouple temperature measurements can be made using linearizations for the following nine standard thermocouples: J, K, E, T, N, R, S, B, C. You specify what type of thermocouple is connected to the channel. The reference temperature sensor is built into the Input Module. The instrument applies compensation automatically for thermocouple channels. Open thermocouple detection is indicated by "otc" in the left display. The thermocouples are further described in Table 3-14.
