5.3 Seleção de intervalo
The YK-37UVSD offers two measurement ranges: 2 mW/cm² and 20 mW/cm². The meter typically auto-ranges, but you may be able to manually select a range using the DEFINIR button or a combination of buttons as described in the on-screen menu.
5.4 Função de retenção de dados
Pressione o SEGURAR botão (frequentemente combinado com FUNC/NEXT) to freeze the current reading on the display. Press it again to release the hold function.
5.5 Ajuste Zero
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 ZERO button to calibrate the meter to zero.
5.6 Data Logging (SD Card)
To initiate real-time data logging to the SD card:
- Certifique-se de que um cartão SD esteja inserido.
- Pressione o MADEIRO button. The display will indicate that logging has started.
- Para interromper o registro de logs, pressione o MADEIRO botão novamente.
- 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. Manutenção
6.1 Limpeza
Wipe the device and probes with a soft, dry cloth. For stubborn dirt, a slightly damp Pode-se usar um pano com detergente neutro, garantindo que nenhum líquido entre no aparelho. Não utilize produtos de limpeza abrasivos ou solventes.
