5.4 وظيفة الاحتفاظ بالبيانات
اضغط على يمسك button (often combined with FUNC/NEXT) to freeze the current reading on the display. Press it again to release the hold function.
5.5 التعديل صفر
For accurate measurements, especially in low light conditions, a zero adjustment may be necessary. With the probe covered or in a dark environment, press the صفر button to calibrate the meter to zero.
5.6 Data Logging (SD Card)
To initiate real-time data logging to the SD card:
- Ensure an SD card is inserted.
- اضغط على مسجل button. The display will indicate that logging has started.
- To stop logging, press the مسجل الزر مرة أخرى.
- Data is saved in a format compatible with spreadsheet software for easy analysis.
5.7 Type K Temperature Measurement
The YK-37UVSD also supports Type K thermocouple temperature measurements. Connect a Type K thermocouple probe (sold separately) to the designated input. Use the FUNC/NEXT button to switch to temperature measurement mode.
6. الصيانة
6.1 التنظيف
Wipe the device and probes with a soft, dry cloth. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the device. Do not use abrasive cleaners or solvents.
