Why won’t my EM61 files open on the DAT61MK2 program?

Why won’t my EM61 files open on the DAT61MK2 program? EM61 files are stored in the data logger as a different file type than the DAT61MK2 program can open.  If the files that you are trying open have the .R61 extension, they will need to be converted to .M61 extension to open in the DAT61MK2 program. Assuming the DAT61MK2 program is …

Static Background Post

When performing the Static Background Test, why does the EM61 response vary so much?

A little variation in the EM61 response may not be problem if looking for large response targets. However, when looking for smaller targets, baseline measurements must have as little variation as possible. So why are your EM61 readings varying more than+/-1.5 mV? Good question! I don’t know. That’s for you to discover. Variances as small as +/- 1.5 mV can happen …

Why won’t my EM-31 files open on the DAT31 program?

Why won’t my EM-31 files open on the DAT31 program? Well, I promise, it’s not because they don’t like you. However, EM-31 data logger files (.R31) are a different flavor than the DAT31 program likes. So, they have to be converted to DAT31 program files with the .G31 file extension. To open EM-31 files collected on the EM-31-MK2 in the …

EM Noise Post

What is EM-61 noise?

There are four different kinds of EM-61 Noise. Determining the source of noise is important because a target response can only be established when the response is greater than the background noise. Instrument EM-61 Noise The EM-61 was made by design to have little instrument noise. However, the instrument itself is not noise free. A well calibrated and maintained EM-61 …
