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 veri-
fication 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.
GBefore 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

ment on the European Economic Area
Working with CPA2P, CPA26P…
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 tem-
perature 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 tempera-
ture 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.
