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 settings 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. See “Enable refresh hold” on page 126 for more 
information on configuring the refresh hold settings.
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.
Set the variation to “OFF” in the utility menu to enable data hold. See 
“Enable data hold” on page 127 for more information. 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.
If the reading value is unable to reach a stable state (when exceeding the 
preset variation), the reading value will not be updated.
