5.2 Changing Measurement Units (fc/lx)
Tobetsa ea fc/lx button to toggle between foot-candles (fc) and lux (lx) units. The selected unit will be indicated on the display.
5.3 TSHOARA Mosebetsi
Tobetsa ea TS'EPA button to freeze the current reading on the display. Press it again to release the hold and resume live measurements.
5.4 Zero Adjustment (CAL)
Ho etsa phetoho ea zero:
- Place the light sensor in a completely dark environment (e.g., cover it with the protective cap or place it in a dark box).
- Tobetsa ea KALA button. The display should show "0.00" or a value very close to zero.
- If the display does not show zero, repeat the process.
5.5 Kgetho ya Range
The device typically operates in auto-ranging mode. To manually select a range or cycle through available ranges, press the RANGE button. The display will indicate the active range. Press and hold the RANGE button to return to auto-ranging mode.
