Why my Extech Instruments ExStik II EC400 unit will not turn on?
If your Extech Instruments Measuring Instruments unit isn't turning on, the batteries may be low, dead, or installed with incorrect polarity. Try replacing the batteries, making sure to observe the correct polarity when installing them.
What to do if my Extech Instruments Measuring Instruments shows a 'BAT' message?
If your Extech Instruments Measuring Instruments displays a 'BAT' message, it means the batteries are low. Replace the batteries to resolve this issue.
How to fix frozen reading on Extech Instruments ExStik II EC400 Measuring Instruments?
If the reading on your Extech Instruments Measuring Instruments is frozen, the unit might be in “HOLD” mode. Press the MODE/HOLD key to exit this mode.
Why Extech Instruments Measuring Instruments unit will not calibrate in conductivity mode?
If your Extech Instruments Measuring Instruments unit isn't calibrating in conductivity mode, it could be due to several reasons: contaminated conductivity standards (use fresh standards), a dirty probe (clean the conductivity probe), a damaged conductivity probe (replace the electrode), or trapped air bubbles (tap or stir to release them).
What to do if Extech Instruments ExStik II EC400 unit does not respond to key presses?
If your Extech Instruments Measuring Instruments unit isn't responding to key presses, it may be due to an internal fault. Try performing a hard reboot: remove the batteries, hold the ON/OFF switch down for 5 seconds, and then replace the batteries.
