Error about electrical signal or noise

Before you move on

You went through Qualification and your BactoBox® setup passed both phase A (QC vial) and phase B (dilution vial).

Is this not the case? Then let's take a step back. Did qualification fail? Does your BactoBox® not even power on?

The measurement triggers an error about electrical signal or noise

You run the Measure program but it gives an error about the electrical signal or noise instead of a concentration.

Error codes 1000–1199 (both inclusive) relate to the electrical signal or electrical noise.

Let's narrow it down. We know that your BactoBox® setup works since it passes qualification. In other words, we'll focus our attention on your sample instead.

Try to dilute your sample more and measure again.

In general, double-check how you prepare your sample for use with BactoBox®. Especially the part about how you get the conductivity into the allowed range. While the page is about electrical conductivity, the same method (dilute your sample more) also apply to errors about electrical signal or electrical noise.
