CHAPTER 4

Getting to Know Your Analyzer

Save Pushbutton

Use the Save pushbutton to save the measurement data together with the current

project template (including all the screen settings and setup information) and the calibration

documentation.

Pressing Save will affect the pause and running states. In both cases the measurement state will

be ‘stopped’ shortly after pressing the pushbutton (Stopped icon

displayed).

Back-erase Pushbutton

For BZ-7222 and BZ-7223 Software:

Use the Back-erase pushbutton to erase the last 5 seconds completely from the measurement.

(This includes, of course, overload indications you would like to erase.)

If used when the current measurement is running, then the measurement will be paused. The

Status Field displays Pause, Back erase briefly, and then displays the shortened elapsed time

along with the Paused icon .

For BZ-7224 and BZ-7225 Software:

Pressing the Back-erase pushbutton will start drawing an Exclude Marker on the display,

see section 11.3.2. Pressing it again will stop drawing the marker on the display (toggle

function).

4.4.4 On-screen Feedback and Traffic Light

Feedback is given on screen in the Status Field (Fig.4.2), and the Traffic Light indicates

important states of the analyzer (Table 4.2).
