FAQs

Q: Can I see temperature, humidity, and dew point all at once on the screen during field checks?

A: Yes, the electronic screen displays all three parameters simultaneously. Temperature, relative humidity, and dew point update in real time on a single view, so you don't need to manually switch between menus while on-site.

Q: Is the built-in memory for 99 datasets enough, and what happens when it gets full?

A: 99 slots are plenty for standard inspection rounds. When you hit the limit, simply connect the unit to generate and export your spreadsheets to a computer. Once your files are backed up, clear the memory on the device to free up space for your next run.

Q: Why does the new probe feel loose or refuse to tighten properly when I try to install it?

A: That usually happens if the module isn't pushed in far enough. Make sure to align the pins and turn the nut counterclockwise two or three times to engage the threads, then press the probe shaft firmly inward toward the main body until it seats properly before tightening the nut all the way.

Q: Why should I swap out the battery immediately as soon as the low-battery icon shows up? 

A: A weak battery can cause voltage drops that compromise sensor accuracy and stability. Swapping in a fresh 9V battery as soon as the warning appears ensures your readings remain precise—just remember to latch the cover securely afterward.

Q: Can I use isopropyl alcohol or heavy-duty cleaners if the housing gets greasy in the field?

A: Avoid alcohol, harsh solvents, or abrasive chemicals, as they can degrade the protective housing. Stick to a soft cloth lightly dampened with mild soapy water to clean the body, then wipe it dry.
