What to do if my Extech Instruments Measuring Instruments unit will not turn on?
If your Extech Instruments Measuring Instruments unit won't turn on, it could be due to low or dead batteries. Replace the batteries. Also, check if the batteries are installed with the correct polarity; if not, replace them, ensuring correct polarity.
Why does my Extech Instruments Measuring Instruments show a 'BAT' message?
The 'BAT' message on your Extech Instruments Measuring Instruments indicates that the batteries are low and need to be replaced.
What to do if my Extech Instruments Measuring Instruments reading is frozen?
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.
What does 'RENEW' message mean on my Extech Instruments Measuring Instruments?
The “RENEW” message on your Extech Instruments Measuring Instruments indicates that the pH sensor needs recalibration. Use fresh buffers to recalibrate the unit. If the pH sensor slope has fallen below acceptable limits, consider replacing the electrode.
Why won't my Extech Instruments Measuring Instruments calibrate in pH mode?
If your Extech Instruments Measuring Instruments unit won't calibrate in pH mode, possible causes include: a low pH slope (replace the electrode), a clogged or contaminated reference junction (clean the junction), a damaged or worn out sensing membrane (replace the electrode), or contaminated pH buffers (use fresh buffers).
Why won't my Extech Instruments Measuring Instruments calibrate in conductivity mode?
If your Extech Instruments Measuring Instruments unit won't calibrate in conductivity mode, the issue might be due to 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 air bubbles).
What to do if my Extech Instruments Measuring Instruments unit will not respond to any key presses?
If your Extech Instruments Measuring Instruments unit does not respond to key presses, perform a hard reboot. To do this, remove the batteries, hold the ON/OFF switch down for 5 seconds, and then replace the batteries.
