To Use Reading Hold

The reading hold feature allows you to capture and hold a stable

 

reading on the display. When a stable reading is detected, the

multimeter emits a beep and holds the value on the display.

To adjust the reading hold sensitivity band, use the TRIG menu.

reading hold is enabled.

•Reading hold has an adjustable sensitivity band to allow you to select which readings are considered stable enough to be displayed. The band is expressed as a percent of reading on the selected range. The multimeter will capture and display a new value only after three consecutive readings are within the band.

•The default band is 0.10% of reading. After enabling reading hold,

you can choose a different band by pressing Shift >

(Menu Recall). This takes you to the “READ HOLD” command in the TRIG MENU (only if reading hold is enabled).

Go down to the “parameter” level, and then select a value: 0.01%, 0.10%, 1.00%, or 10.00% of reading.

•The sensitivity band is stored in volatile memory; the multimeter sets the band to 0.10% of reading when power has been off or after a remote interface reset.
