What to do if Hach 2100Q Measuring Instruments says 'Standard value out of range'?
If the Hach Measuring Instruments displays 'Standard value out of range. Insert standard and push Read', it means an incorrect standard value was used for the reading. Insert the appropriate standard and read again.
What to do if Hach 2100Q Measuring Instruments shows 'Low Battery'?
If the Hach Measuring Instruments displays 'Low Battery!', replace the batteries with new ones. Alternatively, if you're using rechargeable batteries, connect the USB/power module.
Why does my Hach Measuring Instruments say 'Overrange'?
If the Hach Measuring Instruments displays 'Overrange!', it means the turbidity is too high, likely from calibrating with RapidCal only. To fix this, calibrate the upper range or dilute the sample.
What to do if Hach Measuring Instruments says 'Close lid and push Read'?
If the Hach Measuring Instruments shows 'Close lid and push Read', it means the lid is open or the lid detection failed. Ensure the lid is closed during reading and re-read.
How to fix 'USB module memory full' error on Hach Measuring Instruments?
If the Hach Measuring Instruments displays 'USB module memory full. Delete data and try again', it means the data storage is full. Here's how to resolve it: 1. Connect the USB/power module to your computer. 2. Download the stored data to your computer. 3. Delete the Data Log on the module.
What to do if Hach 2100Q prompts to disconnect the USB cable?
If the Hach Measuring Instruments displays 'Please disconnect the USB cable from your computer', it means the data storage isn't responding while connected to both the meter and the computer. Disconnect the USB cable from the meter and try sending the data again.
Why Hach 2100Q shows 'Detector signal too low'?
If the Hach Measuring Instruments shows 'Detector signal too low!', it indicates insufficient light on the 180° detector. Check for any obstructions in the light path and inspect the lamp.
What does 'Please check the lamp!' mean on Hach 2100Q Measuring Instruments?
If the Hach Measuring Instruments displays 'Please check the lamp!', it means signals are too low on the 90° and 180° detector. If it's a 2100Q, the lamp is likely defective and needs changing. If it's a 2100Qis, contact technical support.
What to do if Hach 2100Q Measuring Instruments shows 'Temperature too high'?
If the Hach Measuring Instruments displays 'Temperature too high! Switch off instrument', it signifies that the temperature has exceeded the meter's limits (greater than 60 °C or 140 °F). Turn off the meter and allow it to cool down.
What does 'ADC Failure!' mean on Hach 2100Q?
If the Hach Measuring Instruments displays 'ADC Failure!', it indicates a hardware error causing the reading to fail. Try repeating the reading.
