Here is exactly how to use this thing without breaking the probes (the #1 complaint online).

Step 1: The "No Touch" Rule Do not touch the metal probes with your fingers. Your skin's natural oils and electrical conductivity will mess up the readings. Always hold the unit by the plastic top.

Step 2: The "Deep Dive" For accurate moisture and pH, you cannot just poke the surface. Wipe the probes clean, then push them straight down into the soil 2/3 of the way to the base. The probes need to reach the root zone, not just the dusty topsoil. weltouch cy-210b manual

Step 3: Wait for the "Wiggle" Set the switch to MOIST (the water drop icon). Wait 1 minute. The needle will slowly move. If it jumps to 10 instantly? Your soil is dry. If it barely moves? The soil is too loose—press the soil gently around the probe.

After installing the driver, open WelTouch Config.
