Hold
The refresh hold feature allows you to capture and hold a
reading, within the specified variation and threshold values,
on the front panel display. This is useful in situations when
you want to take a reading, remove the test probes, and
have the reading remain on the display.
When a stable reading is detected, the instrument beeps
once (if the beeper is enabled), and holds the reading on the
primary display. You can select the variation through the
Utility menu. The default setting is 10% of the full scale.
A new reading value is updated in the primary display when
the variation of the measured value exceeds the variation
preset in the Utility menu. The instrument beeps once (if the
beeper is enabled) when a reading value is updated.
Set the variation to “OFF” in the Utility menu to enable data
hold. In data hold mode, the reading is not updated even if
the input signal value changes. The reading held will remain
on the display until you exit the hold mode.
N O T E
• If the reading value is unable to reach a stable state (when exceeding
the preset variation), the reading value will not be updated.
• For voltage, current, and capacitance measurements, the reading value
will not be updated when the reading falls below the threshold preset
in the Utility menu.
• For continuity and diode tests, the reading value will not be updated
when an open state is detected.
