As part of my research,I’m hoping to capture relatively simple acoustic metrics, such as pump volume levels, persistence, and reflection, but I was advised that hydromoths can't be calibrated to be compared against one another, and for my study, I am wanting to deploy 5/6 along a transect and need them to be comparable to one another to measure the distance of noise the pump generates. Does anyone have any experience with this at all or have a work-around that I could use as hydromoths are such a good, cost-effective option for my study as a first year PhD!

Hi. When I set the device to custom and describe the time period and date, the device does not record, but when I set it to default, it records. What should I do? As shown in Figure 1, I have set the time manually. However, the clock displays an incorrect time and date. Although I reside in New Zealand, the system shows the wrong date. When I attempt to adjust the time by selecting the local time option, the previously configured time settings are automatically altered (see Figure 2).

Whenever I set my Audiomoth to custom and describe the time period and date, the green is flashing while the red is solid, but nothing records. But whenever I set it to default, it works.
