What is the cause and resolution steps for an Error one (E1) message on a Pocket Colorimeter II?
Summary
Explanation of the E-1 on a PCII.
Answer
Error 1 on a Pocket Colorimeter II is an ambient light error. This error is displayed when the instrument's detector is picking up more light than what it normally picks up from the LED light source.

Most of the time this is caused by the instrument cap not being used as a light shield as instructed in the method and user manual. Make sure that the instrument cap is being used as a light shield, this will resolve this issue is most cases.

If the error message is being displayed while the instrument cap is on, then try replacing the batteries. If replacing the batteries doesn't resolve the error message, then the instrument will require either service or replacement. If this is the case please contact Hach Tech Support.
