Error codes

Table 2 shows the codes that can occur for various reasons. Error codes show instrument

malfunction or user error.

Error

Code

Description Solution

E02 The ISFET pH probe is damaged. Replace the probe. Contact technical support for probe

replacement information.

E03 Clean the probe. Clean the probe. If the error continues, replace the probe.

E04 Glass pH probe slope error. 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.

E06 ISFET pH probe slope error. Clean the probe. Soak in 40 ºC (113 ºF) pH 7.00 buffer for

2 minutes. Calibrate again. If the error continues, replace the

probe.

E07 Clean the probe. Clean the probe. Make sure that no air bubbles on the sensor

surface or foreign objects or materials on the sensor.

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.
