Where:
l Pre-Math - The measurement value before any math operations are done (including NULL).
l Sensor - The raw sensor value; ohms for thermistor/RTD, volts for thermocouple (thermocouple meas-
urements apply to the 34465A and 34470A only).
l Input/Ref - The DC signal voltage and the DC reference voltage measurements.
l Peak - Displays a running history of the minimum peak, maximum peak, and peak-to-peak values of the
input signal. Peak measurements are high-speed (16 µs effective aperture) and are different from the Min,
Max, and Peak-to-Peak values gathered in Statistics.

After making one or more primary measurements for approximately 4 seconds, the DMM makes one
secondary measurement.
For the Peak secondary measurement, the Clear Peaks softkey allows you to clear the accumulated his-
tory of the peak-to-peak function (resets the record of peak values).
