2 Overview

The electronic balance PLC is a light, rugged precision balance suitable for different purposes. The
removable stainless steel pan allows the laboratory balance to be cleaned easily. The calibration of this
precision balance is done by means of external calibration weights (automatic calibration procedure).The
precision balance is equipped with four adjustable feet. If the balance is used in a laboratory, it can be
powered by the external mains adapter (included). In case the balance is used as a mobile weighing
instrument, it can be powered by AA batteries (not included).
Description:
 designed for professional indoor or outdoor weighing.
 High precision, sensitivity and rapid response time (<5 sec.).
 DMS technology and therefore is also suitable for weighing of iron, nickel or other magnetic materials.
 High quality materials and an optimized power supply.
 High reliability and long service life.
 An easy-cleaning, durable and stable shell [with wind protection]. (see chap. "Scope of delivery")
 Removable stainless steel weighing pan on a plastic support.
 Four adjustable feet, a Level Indicator.
 External calibration, zeroing searches, counting function, tare function.
 Different measuring units can be selected via the keypad (g, ct, ozt, oz, GN, dwt, lb).
 Large LCD display with backlight, digit height 15 mm.
 Powered by the external mains adapter or battery (accumulator).

2.1 Proper Use

The balance you purchased is intended to determine the weighing value of material to be weighed. It is
intended to be used as a "non-automatic" balance, i.e. the material to be weighed is manually and
carefully placed in the center of the weighing plate. As soon as a stable weighing value is reached the
weighing value can be read.

2.2 Improper Use

 Do not use the balance for dynamic weighing. In the event that small quantities are removed or added
to the material to be weighed, incorrect weighing results can be displayed due to the "stability
compensation" in the balance. (Example: Slowly draining fluids from a container on the balance.)
 Do not leave permanent load on the weighing plate. This may damage the measuring system.
 Impacts and overloading exceeding the stated maximum load (max) of the balance, minus a possibly
existing tare load, must be strictly avoided. Balance may be damage by this.
 Never operate the balance in explosive environment. The balance is not explosion protected.
 The structure of the balance can not be modified. This may lead to incorrect weighing results, safety-
related faults and destruction of the balance.
 The balance may only be used according to the described conditions. Other areas of use must be
released by G&G in document.

2.3 Control of inspection, measuring and test equipment

As part of quality assurance the measuring-related properties of the balance and the available adjusting
weight must be checked regularly. The responsible user must define a suitable interval as well as the
