What calibration means, why instruments drift, and the terms that get mixed up: calibration range against instrument range, LRV and URV, span, ranging, zero and span interaction, and what belongs in a calibration record.
A 120 tf weighbridge from wiring to corner correction: cable colours, the four power supply rules, cell positioning by address, where tilt error comes from, and the K correction formula worked through.
Commissioning a DS1M or DS3M with BTA-D, KDS-D or VLC-121D cells: addressing one cell at a time, cable colours, grouping, and the calibration steps that matter.
Commissioning the MK-Di01, D2008H and D2008FA with MKCells LU-D or AMCells QS-D cells: identifying the protocol, setting addresses and wiring the bus, step by step on video.
Hi, OK and Lo signalled by colour instead of read from a display. Choosing the relay board, wiring the tower to the DB-25, reading the connector diagrams, and setting the limits.
Fitting a TTL to RS-232 board to a Jadever JCE or JWE: board options, DB-9 to DB-25 pin mapping, serial settings, and the fixed-width ASCII string the scale sends.
You cannot test a digital load cell with an ohmmeter. What to check instead: protocol and brand, the two wiring colour orders, indicator error codes, and why addressing causes most faults.
Simulate an indicator without hardware: create a virtual port pair, send the weight string from Terminal, and find out whether a fault lies in the software or the cable.
Two wires, one output string and three indicator settings. The ASCII and hex forms of the print string, and why a mismatched form name looks like a wiring fault.
CE marking is a manufacturer’s declaration, not a quality award. What it covers, where it is mandatory, and why it does not replace legal metrology approval for trade scales.
