Purpose
The basic weighing function can be
used alone or in combination with
an application program (counting,
weighing in percent, etc.).
Features
– Taring the balance.
– Assigning IDs to weights (as needed).
– Printing weights.
Using Verified Balances as Legal
Measuring Instruments in the EU*:
The type-approval certificate for verifi-
cation applies only to non-automatic
weighing instruments. For automatic
operation with or without auxiliary
measuring devices, you must comply
with the regulations applicable to the
place of installation.
● Before using the balance as a legal
measuring instrument, calibrate and
adjust it at the place of use using the
built-in motorized calibration weight;
for details, see “Calibration/Adjustment"
in this chapter.
$ The temperature range (°C) indicated
on the verification label may not be
exceeded during operation.
Example:
BD BL 200
+10°C to +30°C
0°C to +40°C isoCAL
K

ment on the European Economic Area
Working with LE26P… Models:
Working with the microbalance requires a
steady hand and a smooth, uninterrupted
technique.
Use forceps or other suitable utensil to
place the sample on the weighing pan.
Perform a number of test measurements
before you begin weighing, to allow the
temperature inside the weighing chamber
to adjust to the ambient temperature
outside the chamber. Otherwise, if the
chamber door was closed for a longer
period of time prior to beginning weighing,
the sudden change in temperature inside
the chamber when you open the door
might affect the weight readout. This
is why a series of test measurements is
recommended; the repeated opening and
closing of the weighing chamber door,
at the same rate of speed as will be used
during the actual weighing sequence,
will both compensate this difference in
temperature to some extent and help you
develop a smooth working rhythm.
Place the sample gently on the weighing
pan. The weight readout should stabilize
within 15 to 20 seconds.
The degree of precision attained increases
in proportion as the weighing operations
become more homogenous.
