Maintenance
seca scales with modular NEC-G2 electronics are fitted with a software-
controlled adjustment device that is controlled using the existing operating
elements. When developing the adjustment device, special attention was paid
to the following requirements:
It must be possible to readjust scales without any additional external
equipment/tools.
The readjustment device must be admissible for verification.
It must be possible to readjust the scales without calibrated test weights.
The readjustment device must be protected against inadvertent use.
Scale adjustment can be carried out manually as described in section 0" or
using seca serva 2.0. Manual adjustment will not correct any corner errors.
2.1.2 Calibration Counter / Number of Adjustments
[374|376|378|703|704|634|635|644|645|656|657|664|665|674|675|6
76|677|684|685||264|274|284|285|954|957|959|963]
Scales fitted with the new, modular electronics are equipped with a calibration
counter allowing a software adjustment to be carried out in accordance with the
requirements for verified scales. Each completed adjustment procedure is
registered by the calibration counter, i.e. the number is automatically
incremented by 1. Non-approved scales are also fitted with a counter which
counts the number of adjustments.
2.1.3 Adjustment Mode and Displaying the Calibration Counter

To begin readjustment or to display the calibration counter contents, start the
scale while pressing another key at the same time. The contents of the
calibration counter (i.e. the number of adjustment procedures carried out so far)
are then displayed for 18 seconds (flashing).
While the calibration count is displayed, a key must be kept pressed (for more
than 1.5 seconds) to switch the scale to adjustment mode.
