Specifications
In case of double display the load pacer can be rmly adjusted to force: FO or selection ANW.
In case of selection: ANW the parameters FO,DI,DE and EX can be freely selected.
• Zero Band
If the zeroband is activated changes around the zero point which are smaller than 0,1% referred to the
nal value (option) are suppressed. For calibration the zeroband can be switched off.
The break detection must be switched off in case of tests which are displacemenresp. deformation-con-
trolled or tests during which the ramp is run downwards and in case of calibration. The treshold in %0 of
the machine range corresponds to the force drop, which is necessary to release the break detection.
After starting the display switches from BD to BR. If a printer is connected a test printout (certicate) is
printed automatically. The break detection is reset with RES.
* Function: Break detection due to force decrease. When a specimen breaks the
force decreases. If the level is exceeded, the break is detected.
This level can be set between 1 and 100 %0. The default value is 50 %0. If e.g. hard specimens should
not be destructed too strongly, the level must be set lower. For further information please see “sub-menu
settings”.
• Limiting Values (Option):
* FIX Max. limit at 103% or at the end of the converter range. MAX display.
RES key for deleting.
* 2SP 2 limiting values MIN and MAX, programmable or at the beginning or
the end of the converter range. MIN./MAX. display. RES key for
deleting. Can be switched on and off separately.
* 2NS 2 limiting values MIN and MAX, programmable or at the beginning or
the end of the converter range. MIN./MAX. display. Deleted when
sinking below the programmed hysteresis point by 2%. Can be switched
on and off separately.
As a safety, the limiting values also react at - 4,6% (MIN) and + 104,6% (MAX) of the uncalibrated measuring
range. This corresponds to absolute zero resp. the end of the A/D converter range. This case occurs if
tare point + MIN.-limiting value
or
calibration point + MAX.-limiting value
exceed the converter range.
The maximum and minimum limiting values can be set for the protection of the machine or of the specimen.
In the customer's conguration the maximum and minimum limiting value can be separately switched
on and off and the levels can be programmed as well. Programmable limiting values (2SP, 2NS) can be
set in digits in the range of -3% up to 103%. Switch on with MA.
