How do I know my Pulsoid chip is wet?

A chip must be wet (liquid fully through the pore) before it can measure.

1. Measure the baseline current at 100 mV and at 0 mV.
2. Subtract: corrected baseline = baseline at 100 mV − baseline at 0 mV
3. The chip is wet when the corrected baseline is stable and between 16 and 40 nA. The exact value depends on the chip. P5T chips are usually at the higher end of this range. 

Also check the RMS noise is below 100 pA at 250 ksps.

Not wetting? Use the PAD or syringe tool, or see Section 5.6 of the user manual.
