1. Inngangur
The Extech Instruments HW30 HeatWatch is a multi-function stopwatch designed to provide essential environmental data alongside precise timing capabilities. This device displays digital up/down timer functions, current temperature, humidity, and calculates the heat index, which indicates how hot it feels when humidity is combined with the actual temperature. It is an ideal tool for monitoring conditions in various environments, particularly those with hot weather. Additional features include a 12/24-hour clock, a standard stopwatch, 30 lap/split memory, and a programmable alarm.

5. Uppsetning
5.1. Uppsetning rafhlöðu
The HW30 HeatWatch requires one Lithium Metal battery for operation. The battery is typically included with the device.
- Finndu rafhlöðulokið aftan á tækinu.
- Use a small screwdriver or coin to open the battery compartment.
- Insert the Lithium Metal battery, ensuring correct polarity (+/-) as indicated inside the compartment.
- Settu hlífina yfir rafhlöðuhólfið aftur og festu það.
Athugið: Fargið notuðum rafhlöðum á ábyrgan hátt í samræmi við staðbundnar reglur.
6. Notkunarleiðbeiningar
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. Grunnaðgerðir og stillingarval
Ýttu á MODE hnappinn til að fletta á milli eftirfarandi birtingarstillinga:
- Tímastilling: Displays the current time (12 or 24-hour format).
- Skeiðklukkustilling: For timing events, including lap/split functions.
- Humidity/Temperature/Heat Index Mode: Shows environmental readings.
- Viðvörunarstilling: For setting and activating the programmable alarm.
6.2. Stilling á tíma og dagsetningu
- Í tímastillingu, ýttu á og haltu inni MODE hnappinn þar til tímastafirnir byrja að blikka.
- Notaðu BYRJA/STOPPA hnappinn til að stilla blikkandi tölustafinn (klukkustundir, mínútur, sekúndur).
- Ýttu á LAP/SPLIT/RESET button to move to the next digit or setting (e.g., 12/24-hour format, date).
- Þegar allar stillingar hafa verið stilltar, ýttu á MODE button to exit setup.
6.3. Using the Stopwatch Functions
- Switch to Stopwatch Mode using the MODE hnappinn.
- Ýttu á BYRJA/STOPPA að hefja tímasetningu.
- Ýttu á 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.
- Ýttu á BYRJA/STOPPA aftur til að gera hlé á skeiðklukkunni.
- Til að halda áfram skaltu ýta á BYRJA/STOPPA. Til að endurstilla, ýttu á LAP/SPLIT/RESET á meðan skeiðklukkan er í biðstöðu.
- Til að kalla fram vistaða hring-/millistíma, ýttu á MYNDATEXTI 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 hnappinn.
- 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. Stilla vekjarann
- Switch to Alarm Mode using the MODE hnappinn.
- Ýttu á og haltu inni MODE hnappinn þar til tölurnar fyrir vekjaraklukkuna byrja að blikka.
- Notaðu BYRJA/STOPPA hnappinn til að stilla blikkandi tölustafinn (klukkustundir, mínútur).
- Ýttu á LAP/SPLIT/RESET hnappinn til að færa sig á milli klukkustunda og mínútna.
- Þegar stilltur er á viðvörunartíma skaltu ýta á MODE hnappinn til að staðfesta.
- Til að virkja eða slökkva á vekjaraklukkunni skaltu ýta á BYRJA/STOPPA button in Alarm Mode. An alarm icon will appear on the display when activated.
