Simple Weighing

Place your sample on the weighing pan (7), and close

the draft shield door. Read off the weight indicated

on the display (28) only after the weight unit (“g”, or a

different

unit selected – see part 2, “Balance

Operating Menu”)

appears as the stability symbol.

Taring

If you wish to use a container or if the weight display

does not indicate 0.000 mg (depending on the

display mode or weight unit selected), zero the display

before you weigh.

To do so, press t key (26).

During taring, you can have the fully automatic draft

shield function either on or off.

For more information on turning this fully automatic

draft shield function on or off by menu code, refer to

part 2, “Balance Operating Menu.”

Important Note for Verified Balances Approved for

Use as Legal Measuring Instruments:

The small circle in the weight display (on the left)

shows that the balance is exactly tared to “0”

(± 0.25 of a scale interval).

Important Note Concerning Verified Balances

of Accuracy Class k

To avoid measuring errors, the respective air density

must be allowed for. The following formula is used to

calculate the mass of the sample:

1– ρ

/8000 kg m

–3

m = n

1– ρ

/ρ

m = mass of the sample

= weight readout

= air density during weighing

ρ = density of the sample
