Power supply: 5...30V DC
Voltage measurement range: 5...30V DC
Temperature measurement range: -40...120°C ±0.1°C
RTC accuracy: ±5 ppm (≈13 s/month)
Dimensions: 40mm x 13mm

Operation (two buttons):
In normal mode:
• Right button: switches between the displayed values: Time → Date → Temperature → Voltage → Circular display
- In the circular display, the set values ​​are displayed alternately at set intervals
• Left button: enters settings

In settings mode:
• Left button: steps through settings
• Right button: increases value (cyclically)

1.: Date: (Year) / 2020...2080
2.: Date: (Month.Day)
3.: Time: (Hour:Minute)
4.: Time: (:Second)
5.: Voltage calibration: (0.0u) / -0.5...0.5
6.: Temperature calibration: (Ac: 0) / -5...5
7.: Circular display: (dd: 0) / 0, 1, 3
- 0: time → temperature → voltage
- 1: time → temperature
- 3: time → voltage
8.: Switching speed: (dF: 1) / 1...9
9.: Display brightness: (LL: 3) / 1...3
10.: Dynamic brightness (day / night): (AL) / 0, 1 / 07:00...20:00
Minimum brightness at night, maximum brightness during the day, the brightness setting is irrelevant in this case (point 9)
11.: Time format: (FF:24) / 12, 24
12.: save and exit

Automatically saves and exits after 30 seconds of inactivity
