Mean Calculation, Menu system, Qd Mode, Rl Mode

Entering Measurement id:

To enter / edit the sequence id press the button when in home position.

Use the button to scroll through the alphabet in direction A..Z (starting with the space character), 0..9. The button will scroll through the alphabet in opposite direction.

When the wanted character is shown press the button to advance to the next position. You have to step through all 6 positions before the sequence id function will be accepted.

When typing a new sequence id text or editing an old one, the sequence number is reset to 0. When all 6 positions are set to space the sequence id function is undefined and no longer in- cluded in the log nor shown in the display. This can also be done using the Menu command: Disable Id

Mean Calculation

The instrument automatically calculates and displays the mean (average) value of 2 or more measurements when the Mean Calc function is ON. See Menu system.

If the Rl / Qd value shown in the display contains a decimal point (.) then the shown value is a mean value. The number of samples is displayed for one second after each measurement.

Press to redisplay this information.

The following actions will clear the mean calculation:

•Clear Top Log function

•Toggling the Rl / Qd modes

•Clear mean (from menu)

•New calibration

Measurements stored in the log are not the displayed average values but the actual measure- ment value.

If a measurement error occurs (e.g. Rl / Qd out of limit) a message: “Error! Can’t calc new mean!” is shown in the display. Both measurements (Rl / Qd) are ignored, a new average is not calculated and the sample number is not incremented. The measurements how ever are stored in the log as normal.
