Why won't my Extech Instruments Multimeter turn on?
If your Extech Instruments Multimeter doesn't turn on, it could be due to low or dead batteries. Replace the batteries. Another possibility is that the batteries were installed with incorrect polarity. Replace the batteries, making sure to observe the correct polarity.
What to do if my Extech Instruments Multimeter shows a 'BAT' message?
If your Extech Instruments Multimeter displays a 'BAT' message, it means the batteries are low. You should replace them to resolve this issue.
How to fix a frozen reading on my Extech Instruments Multimeter?
If the reading on your Extech Instruments Multimeter is frozen, the unit might be in “HOLD” mode. To exit this mode, press the MODE/HOLD key.
Why won't my Extech Instruments Multimeter calibrate in pH mode?
If your Extech Instruments Multimeter won't calibrate in pH mode, there are several potential causes: a low pH slope, which suggests you replace the electrode; a clogged or contaminated reference junction, which requires cleaning the junction; a damaged or worn-out sensing membrane, also suggesting electrode replacement; or contaminated pH buffers, advising the use of fresh buffers.
What to do if my Extech Instruments ExStik EC505 Multimeter won't calibrate in conductivity mode?
If your Extech Instruments Multimeter won't calibrate in conductivity mode, consider these possibilities: contaminated conductivity standards, suggesting the use of fresh standards; a dirty probe, advising you to clean the conductivity probe; a damaged conductivity probe, recommending electrode replacement; or trapped air bubbles, which can be released by tapping or stirring.
What does the 'RENEW' message mean on my Extech Instruments Multimeter?
If your Extech Instruments Multimeter displays a 'RENEW' message, it indicates that the pH sensor needs recalibration. Use fresh buffers to recalibrate the unit. Alternatively, the pH sensor slope may have fallen below acceptable limits, in which case the electrode should be replaced.
