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.

G 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 and

Adjustment" in the next 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

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 propor-

tion as the weighing operations become

more consistent.
