Name and type of instrument and modules
The weighing instrument is designated KFA.. / KFE.. / KFC... It is a system of modules consisting of
an electronic indicator, connected to a separate load receptor and peripheral equipment such as printers
or other devices, as appropriate. The instrument is a Class III or IIII, self-indicating weighing instru-
ment with single-interval, multi-range or multi-interval, an external AC mains adapter, and an internal
rechargeable battery (optional).

ment with single-interval, multi-range or multi-interval, an external AC mains adapter, and an internal
rechargeable battery (optional).
The indicators consist of analogue to digital conversion circuitry, microprocessor control circuitry,
power supply, keyboard, non-volatile memory for storage of calibration and setup data, and a weight
display contained within a single enclosure.

Construction
2.1.1
Indicator
The indicator is specified in section 3.1.
Enclosures and keyboard
The indicators are housed in an enclosure made of either ABS plastic (model KFA-TM / KFC-TM) or
stainless steel (Model KFE-TM).
stainless steel (Model KFE-TM).
The front panels of the indicator comprise of
-
LCD display with backlight having appropriate state indicators and 6 digits (22 mm high)
-
keyboard containing 5 keys used to enter commands or data into the weight indicator, plus a
key for turning the indicator on/off. Each key is identified with a name and/or pictograph.

Electronics
The instruments use a single printed circuit board, which contains all of the instrument circuitry. The
metrological circuitry for the models of weight indicator is identical.
metrological circuitry for the models of weight indicator is identical.
All instrument calibration and metrological setup data are contained in non-volatile memory. The
power supply accepts an input voltage of 9 - 12 VDC from the external power adapter, with input from
230 VAC 50 Hz. The indicator produces a load cell excitation voltage of 5 VDC.

Functions
The weight indicating instruments are microcontroller based electronic weight indicators that require
the external connection of strain gauge load cell(s). The weight information appears in the digital dis-
play located on the front panel and may be transmitted to peripheral equipment for recording, process-
ing or display.
