HOLDING A STABLE MEASUREMENT (TOUCH HOLD)

The Touch Hold function captures the next stable measurement and a beep indicates that a stable measurement has been made. When the Touch Hold function is turned on, the numeric display is frozen (held) until a stable measurement is detected. Stable measurements are defined as:

•Within +/-100 display counts for 1s.

•Above 200 display counts for dc signals.

•Above 300 display counts for ac signals.

•Below overload (OL) in Ω and diode test.

TOUCH HOLD appears in the top right of the display when the function is active.

NOTE

The Touch Hold function is not available in Min Max.

The following procedure can be used forTouch Hold:

1.Press and measure the signal.

2.Wait until the ScopeMeter test tool produces a beeper signal to indicate a stable signal.

3.Remove the measuring leads and read the result from the display.

4.Measure a new signal, wait for the beeper, remove the leads, and read again.

5.Press to return to normal measurement mode.
