DESCRIPTIVE ANNEX
Introduction:
The instruments, designated the CCT-M, CKT-M, and SWZ, comprise a digital weight indicator connected to a load cell to form a family of single or dual interval, Class III, non-automatic weighing instruments. The instruments are self-indicating and mains-powered with an optional, internal rechargeable battery for back-up power.
The instruments may be used for direct sales to the public.
Model variants and designation:
The scale model group names are CCT-M, CKT-M, SWZ, within the scale model group names are various versions depending on capacity and construction, so for example there is a model CCT-4M which is a member of the CCT-M scale group, the 4 in the model name represents the maximum capacity in kg. Another example is SWZ-15D, this is a 15kg Dual interval scale, 15 represents the 15kg capacity and the D represents the Dual interval. There are also rear Pillar versions of the scale model groups which are denoted with a P at the end of the model name, for example SWZ-15DP, is a 15kg capacity, dual interval with a pillar rear display.
Main features:
ABS Plastic enclosure
Stainless steel weighing pan
LCD Segment display
Operator keypad with numerical, navigation and function keys
Bubble level indicator
Four adjustable rubber feet
Optional additional pole-mounted or rear display (SWZ only)
Devices:
Initial zero setting device on power up
Semi-automatic zero setting
Semi-automatic subtractive tare weighing
Zero-indicator
Zero-tracking
Net indication
- Indication of stable equilibrium
Net indicator
Printing
Weight accumulation
Price computing (SWZ only)

Load cell:
Any compatible load cell(s) may be used providing the following conditions are met:
There is a respective OIML Certificate of Conformity (R60) for the load cell.
The certificate contains the load cell types and the necessary load cell data required for the manufacturer's declaration of compatibility of modules, and any particular installation requirements. A load cell marked NH is allowed only if humidity testing to R76 has been conducted on this load cell.
The compatibility of the load cells and indicator is established by the manufacturer by means of the compatibility of modules calculation at the time of verification.
The load cell transmission conforms to a standard type.
Interfaces:
- Load cell connection (internal only)
RS232/485
USB
Software:
The software is held in firmware on the circuit board, and has the identification as described below:
| Instrument | Software identification |
| CCT-M | v1.xx |
| CKT-M | v1.xx |
| SWZ | v1.xx |
with xx reflecting non-legally relevant changes. The software version number is displayed at power-up.
Download of software is prevented by hardware sealing. The program is fully embedded on the integrated circuit on the PCB and downloads aren't possible without removing the integrated circuit.
Access to the legally relevant parameters is prevented by hardware sealing. A jumper must be fitted on the PCB to gain access to legally relevant parameters. Once the jumper is fitted, a service password is required to access legally relevant parameters.
Sealing:
The entire casing is secured by a tamper proof label over an underside case screw.
Access to the jumper connection described above is secured by a tamper proof label over the access hole.
Alternatives:
There are currently no authorised alternatives.
