(9) The manual setting value for reference end’s temperature - mAn.tmp: Set
the menu parameter mAn.tmp to the temperature value of the constant
temperature oven in case of adopting the MAN compensation mode.
When verify the indicating value errors for the thermocouple of the instrument,
sometimes it is inconvenient to use INT compensation mode, and the MAN
compensation mode can be used. With regard to the MAN compensation mode,
use copper conductor wires to connect the instrument and standard mV signal
source, verify the basic indicating value errors, and then verify the compensation
errors of the interior (INT) reference ends. Finally, errors with the INT
compensation mode are the synthesis of the basic indicating value error and
compensation error.
(10) The Upper and Lower Limit Alarm —LowEr.L and UPPEr.L:
1) The lower limit alarm value - LowEr.L: Once the measured value x is
smaller than the set lower limit value LowEr.L, LOAL alarm will be generated
immediately. After the LOAL occurs, only the measured increases to no less
than (LowEr.L + alarm hysteresis error δ) can the LOAL alarm be released.
The alarm sound will stop automatically after 60 seconds, or can be
deactivated by pressing any key.
2) The upper limit alarm value - UPPEr.L: Once the measured value x is larger
than the set upper limit value UPPEr.L, HIAL alarm will be generated
immediately. After the HIAL occurs, only the measured reduces to no more
than (UPPEr.L- alarm hysteresis error δ) can the HIAL alarm be released. The
