Error
Code
Description Solution
E08 Too long to calibrate. Signal is not
stable during calibration.
Clean the probe. Disconnect stirrers and other AC power
sources. Make sure that the calibration solution temperature
is constant. Replace the probe if the error continues.
E13 The ISFET pH probe temperature
sensor is damaged.
Replace the probe. Contact technical support for probe
replacement information.
E14 The battery is extremely low. Replace the batteries immediately. Damage to the accuracy
and function of the meter could have occurred.
E15 Replace the battery immediately.
The accuracy and function of the
meter could be compromised.
Contact technical support for service information.
E20 The conductivity temperature
sensor is damaged.
Replace the probe. Contact technical support for probe
replacement information.
E25 The slope is smaller than 60% or
larger than 140% of the nominal.
Replace DO probe membrane and fill solution. Replace the
probe if the error continues. Nominal = 0.1822 ppm/mV.
E26 The mV reading is more than
±10 mV from nominal.
Replace DO probe membrane and fill solution. Replace the
probe if the error continues. Nominal = 0.0 mV at 0%
saturation; 45mV at 100%.
E27 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.
E28 Barometric pressure sensor error Contact technical support for repair information.
E30 ISE electrode calibration error The slopes are not the same sign or are not within 25% of
each other. Calibrate again in the correct solutions.
E40 Unrecognized host command Command from a host PC is not found. Use only valid
commands.
E42 Invalid input The value entered during the setup is invalid. Enter a
different value.
E44 No probe is installed No probe is installed for the applicable parameter. Set the
meter power to off. Install the correct probe. Set the meter
power to on.
