Hold Function

You can freeze the measured value on the display.

Maximum value and minimum value can also be

measured by using the hold function in

combination with the measurement mode.

The type of measured value that is retained with the

holding function varies depending on the

measurement mode.

"HOLD MODE" (page 5-9)

• The hold function retains only the display of the

measured value. The graph is continuously

displayed even if the hold function is enabled.

• On the pause screen, only the graph display is

retained and the measured value is continuously

displayed.

"Pause Screen" (page 4-10)

The hold function is enabled or disabled in OUT1 and

OUT2 at the same time.

It cannot be enabled or disabled in OUT1 or OUT2

independently.

The hold function can be operated by using the

following means:

• Remote control console

• External I/O terminal

• RS-232C

Remote control console

If you press the [HOLD] button on the remote control

console, the measured value is retained. If you press the
