The requirement for a correct area calculation is that the first

measured length (for example the ceiling height A) is

identical for all sub-areas.

Grade measurement (see figure G)

Press the button for grade measurement (3) to bring up the

indicator for grade measurement

on the display. The rear

of the measuring tool serves as the reference level. Press the

button for grade measurement (3) again to use the sides of

the measuring tool as a reference level and rotate the display

view by 90°.

Press the measuring button (2) to fix the measured value

and transfer it to the measured value memory. Press the

measuring button (2) again to continue the measurement.

If the display flashes during measurement, the measuring

tool has been tipped too heavily to the side.

If the "digital spirit level" function is activated in the basic

settings, the grade value is also displayed in the other meas-

uring functions in line (d) of the display (1).

Timer function

The timer function is useful when the measuring tool should

be kept stationary during measurement, for example.

Press and hold the button for the timer function (6) to bring

up the indicator on the display.

The time period between triggering the timer and starting

measurement is displayed in the measured value line (a).

The time period can be set between 1–60 seconds by press-

ing the plus button (11) or minus button (5).

The measurement is made automatically after

the set time period has expired.

The timer function can also be used for dis-

tance measurements within other measuring

functions (e.g. area measurement). It is not possible to add

or subtract measuring results or carry out continuous meas-

urement.

List of the last measured values

The measuring tool stores the last 20 measured values and

their calculations and displays them in reverse order (with

the most recent measured value displayed first).

To retrieve the saved measurements, press the

button (7). The result of the last measurement

appears on the display, along with the indic-

ator for the measured values list (e) and with

storage space for the numbering of the dis-

played measurements.

If no further measurements are saved upon pressing the but-

ton (7) again, the measuring tool switches back to the last

measuring function. Press one of the buttons for the measur-

ing functions to exit the list of measured values.

To permanently save the currently displayed measured

length value as a constant, press and hold the button for the

list of measured values (7) until "CST" is shown on the dis-

play. An entry in the list of measured values cannot be retro-

spectively saved as a constant.

To use a measured length value in a measuring function (e.g.

area measurement), press the button for the list of meas-

ured values (7), select the desired entry and confirm it by

pressing the results button (6).

Deleting measured values

Briefly pressing the button (8) will delete the last measured

value in all measuring functions. Repeatedly pressing the

button briefly will delete the individual measured values in

reverse order.

To delete the currently displayed entry in the list of meas-

ured values, briefly press the button (8). To delete the com-

plete list of measured values and the constant "CST", press

and hold the measured value list button (7) and at the same

time briefly press the button (8).

In the wall area measurement function, a brief first press of

the button (8) will delete the last individual measured value;

a second press will delete all lengths B

; a third will delete

the ceiling height A.

Adding measured values

To add measured values together, first perform any meas-

urement or select an entry from the list of measured values.

Next, press the plus button (11). "+" will appear on the dis-

play as confirmation. Then perform a second measurement

or select another entry from the measured value list.

Press the results button (6) to retrieve the sum

of both measurements. The calculation is

shown in the measured value lines (a) and the

sum is displayed in the result line (c).

When the sum has been calculated, you can add more meas-

ured values or measured value list entries to this result if you

press the plus button (11) before each measurement. Press

the results button (6) to end the addition.

Information on addition:

– Mixtures of length, area and volume values cannot be ad-

ded together. For example, if a length value and an area

value are added together, "ERROR" will appear briefly on

the display when the results button (6) is pressed. The

measuring tool will then switch back to the most recently

active measuring function.

– The result of a measurement (e.g. volume value) is always

added; for continuous measurements, the measured

value displayed in the result line (c) is added. It is not

possible to add individual measured values from the

measured value lines (a).

Subtracting measured values

To subtract measured values, press the minus

button (5); "-" will appear on the display as

confirmation. The subsequent steps are the

same as for the "Adding measured values" sec-

tion.
