6.1. Gweithrediad Sylfaenol a Dewis Modd

Gwasgwch y MODD button to cycle through the following display modes:

  • Modd Amser: Displays the current time (12 or 24-hour format).
  • Modd Stopwats: For timing events, including lap/split functions.
  • Humidity/Temperature/Heat Index Mode: Shows environmental readings.
  • Modd Larwm: For setting and activating the programmable alarm.

6.2. Gosod yr Amser a'r Dyddiad

  1. Yn y Modd Amser, pwyswch a daliwch y MODD botwm nes bod y digidau amser yn dechrau fflachio.
  2. Defnyddiwch y DECHRAU/STOPIO button to adjust the flashing digit (hours, minutes, seconds).
  3. Gwasgwch y LAP/SPLIT/RESET button to move to the next digit or setting (e.g., 12/24-hour format, date).
  4. Unwaith y bydd yr holl osodiadau wedi'u ffurfweddu, pwyswch y MODD button to exit setup.

6.3. Using the Stopwatch Functions

  1. Switch to Stopwatch Mode using the MODD botwm.
  2. Gwasgwch DECHRAU/STOPIO i ddechrau amseru.
  3. Gwasgwch LAP/SPLIT/RESET to record a lap or split time. The display will momentarily show the recorded time while the stopwatch continues to run in the background.
  4. Gwasgwch DECHRAU/STOPIO eto i oedi'r stopwats.
  5. I ailddechrau, pwyswch DECHRAU/STOPIO. I ailosod, pwyswch LAP/SPLIT/RESET tra bod y stopwats wedi'i oedi.
  6. To recall stored lap/split times, press the COFIO button in Stopwatch Mode. Use LAP/SPLIT/RESET to scroll through memory.

6.4. Humidity, Temperature, and Heat Index Measurement

The HW30 automatically measures and displays humidity, temperature, and calculates the heat index in the dedicated mode.

  1. Switch to Humidity/Temperature/Heat Index Mode using the MODD botwm.
  2. The display will show the current humidity percentage, temperature (in °F or °C), and the calculated heat index.
  3. Allow a few minutes for the sensors to stabilize and provide accurate readings, especially when moving the device between environments with different conditions.

6.5. Gosod y Larwm

  1. Switch to Alarm Mode using the MODD botwm.
  2. Pwyswch a dal y MODD botwm nes bod y digidau amser larwm yn dechrau fflachio.
  3. Defnyddiwch y DECHRAU/STOPIO button to adjust the flashing digit (hours, minutes).
  4. Gwasgwch y LAP/SPLIT/RESET button to move between hours and minutes.
  5. Unwaith y bydd yr amser larwm a ddymunir wedi'i osod, pwyswch y MODD botwm i gadarnhau.
  6. I actifadu neu ddadactifadu'r larwm, pwyswch y DECHRAU/STOPIO button in Alarm Mode. An alarm icon will appear on the display when activated.

7. cynnal
