What to do if my Hach H160G Measuring Instruments show an unstable reading?
If you are experiencing unstable readings with your Hach Measuring Instruments, several factors could be the cause. First, the probe might be dirty, so try cleaning it. Also, make sure to clean the probe contacts on the cable connector and the meter using methanol on a cotton swab, letting it dry completely before reconnecting. Other potential issues include no flow in the reference junction (clean the warm buffer), an ISFET probe that isn't correctly hydrated (soak it in pH 7.00 buffer for at least 5 minutes), interference from other devices (remove them), or direct sunlight (shield the probe). Note that stable readings may not be possible in very low ionic strength solutions or if the pH or temperature of the solution is changing.
What does E14 error mean on Hach H160G?
Error E14 on your Hach Measuring Instruments indicates that the battery is extremely low. Replace the batteries immediately to prevent potential damage to the accuracy and function of the meter.
How to fix a Hach H160G with no display?
If your Hach Measuring Instruments have no display, it could be due to a couple of reasons. First, check if the automatic shutdown feature has turned the power off; if so, simply set the power back to on. If that's not the issue, the problem might be a lack of power, in which case you should replace the batteries.
What does E04 error mean on Hach H160G Measuring Instruments?
Error E04 indicates a glass pH probe slope error, meaning the slope is smaller than 85% or larger than 102% of 59.16 mV per pH unit. Clean the probe. If the error continues, replace the probe.
What does E06 error mean on Hach H160G?
Error E06 indicates an ISFET pH probe slope error. Clean the probe, soak it in 40 ºC (113 ºF) pH 7.00 buffer for 2 minutes, and calibrate again. If the error continues, replace the probe.
What does E20 error mean on Hach H160G?
Error E20 indicates that the conductivity temperature sensor is damaged. Replace the probe. Contact technical support for probe replacement information.
What does E44 error mean on Hach H160G Measuring Instruments?
Error E44 indicates that no probe is installed for the applicable parameter. Set the meter power to off. Install the correct probe. Set the meter power to on.
What does E40 error mean on Hach Measuring Instruments?
Error E40 indicates an unrecognized host command. This means a command from a host PC is not found. Use only valid commands.
What does E27 error mean on Hach Measuring Instruments?
Error E27 indicates a DO probe temperature error. Attach the temperature sensor to the 3.5 mm phono jack. DO readings are highly temperature dependent, and a temperature sensor must be attached.
