In the measurement interface, press Menu to enter the first level menu, and ESC to return to the measurement
interface. Under the first level menu, you can use the up and down keys to select the corresponding options. When
you press Menu, you will enter the second level menu. The up and down keys will adjust the corresponding
options. After adjustment, press Menu to save the settings and return to the first level menu. After adjustment,
press ESC to not save and Return to the first level menu.

1
Measurement interval
4,6,8,10 S
2
Calibrate 0
Calibration 0 returns to the main page successfully, EE0 is displayed if it
fails
3
Brix corresponding to the upper limit
of 20mA in the current 4~20mA
Default value depend on the measurement range
4
Decimal places
0 , 1 , 2
5
Display temperature, refractive index
or polling display
1=temperature, 2=refractive index, 3=polling display
6
Mode-S measurement stability
1, 2, 3, 4, 5 total 5 gears
7
Temperature correction in units of 0.1
Increase or decrease by 0.1
8
Brix corresponding to the lower limit
4mA in the current 4-20mA
Default 0%
9
Temperature 4-20mA upper limit 1 as
the unit (Reserved functions)
Increase or decrease the upper limit of the solution 4-20mA output by 1.
When the temperature value is greater than or equal to the upper limit,
the output is 20mA, and the value range is -10-130
10
Temperature 4-20mA lower limit 1 as
the unit (Reserved functions)
Increment or decrement the lower limit of the 4-20mA output of the
solution by 1, when the temperature value ≥ the upper limit, the output
4mA, the value range is -10-130
11
The alarm high limit is 1 as the unit
When the measured concentration exceeds the high limit, the display
flashes quickly, and the value range is 0-100 When the setting value is
greater than 95, it is equivalent to turning off the alarm output
12
Alarm low limit 1 as unit
Increase or decrease by 1 when the measured concentration is lower
than the low limit, display
Slow flashing, when the set value is less than 0, it is equivalent to
turning off the alarm output
13
Device ID address
Default is 1
