On/Off function GB

Press briefly

If! appears, deactivate with

Automatic shut-off after 8 min. of inactivity

Press and hold for 3 sec. to switch off the device

Display lighting on/off

Measurement

Hold the device without protective cap in the sample water to be measured so that the device is immersed in the sample water no higher than the seal ring.

The measurement is displayed.

Briefly press! to freeze/release the measurement

Press and hold for 3 sec. to save the measurement
The storage location (e.g. 01) appears in the display while the button is pressed

Calibration

The electrode must be rinsed off after each measurement/calibration with distilled water. Recalibrate as necessary. If the temperature is outside of the measuring range, 'ERR' appears. The measuring device automatically returns to measuring mode. When the readout of the standard is more than 30% outside of the standard buffer range, 'ERR' appears.

Autom. recognition of limited to: 100999 ppm; limited to 1 - 10 ppt.

Pull off the protective cap, switch on the device, rinse the electrode with distilled water, then immerse in the calibration solution.

Press Cal for 3 sec.
