6. Nga Tohutohu Whakahaere
This section details the various functions and modes of the HW30 HeatWatch.
Figure 6.1: The HW30 HeatWatch being held, demonstrating its portable and ergonomic design for active use.
6.1. Basic Operation and Mode Selection
Pehia te MODE pātene hei huri i roto i ngā aratau whakaatu e whai ake nei:
- Aratau Wā: Displays the current time (12 or 24-hour format).
- Aratau Tapukati: For timing events, including lap/split functions.
- Humidity/Temperature/Heat Index Mode: Shows environmental readings.
- Aratau Whakaoho: For setting and activating the programmable alarm.
6.2. Te Whakaritenga i te Wa me te Ra
- In Time Mode, press and hold the MODE patene tae noa ki te wa ka timata nga matimati ki te kanapa.
- Whakamahia te TITIAKI/TATA pātene hei whakatika i te mati rarapa (haora, meneti, hēkona).
- Pehia te LAP/SPLIT/RESET button to move to the next digit or setting (e.g., 12/24-hour format, date).
- Kia whirihora nga tautuhinga katoa, pehia te MODE button to exit setup.
6.3. Using the Stopwatch Functions
- Switch to Stopwatch Mode using the MODE pātene.
- Perehi TITIAKI/TATA ki te timata i te wa.
- Perehi 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.
- Perehi TITIAKI/TATA ki te okioki ano i te mataaratanga.
- Hei whakaara ano, pehia TITIAKI/TATA. Hei tautuhi, pehia LAP/SPLIT/RESET i te wā e whakamutua ana te wati mutu.
- To recall stored lap/split times, press the WHAKAMAHI 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.
- Switch to Humidity/Temperature/Heat Index Mode using the MODE pātene.
- The display will show the current humidity percentage, temperature (in °F or °C), and the calculated heat index.
- 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. Te Whakatakoto i te Whakaoho
- Switch to Alarm Mode using the MODE pātene.
- Patohia me te pupuri i te MODE pēhi i te pātene kia tīmata rā anō te kimo o ngā mati wā whakaoho.
- Whakamahia te TITIAKI/TATA button to adjust the flashing digit (hours, minutes).
- Pehia te LAP/SPLIT/RESET button to move between hours and minutes.
- Once the desired alarm time is set, press the MODE pātene hei whakaū.
- Hei whakahohe, whakakore ranei i te whakaoho, pehia te TITIAKI/TATA button in Alarm Mode. An alarm icon will appear on the display when activated.
