shown on the display. There are three types of measurement display panels: the standard,
calendar, and clock display panels. Use MEAS key to cycle through these display panels.

3.4 Saving a Measured Value
There are two ways to save a measured value: holding temporarily and storing as a
record in nonvolatile memory. Measured values stored in nonvolatile memory are not
deleted even by replacing the batteries.
(1) HOLD
If HOLD key is pressed during measurement, the currently measured value is held
temporarily and the displayed value no longer changes. Press HOLD or MEAS key to
return to the measurement mode.
