2. If device is to be connected to other devices (e.g. via serial interface) the circuitry has to be designed most carefully. Internal connection in third party devices (e.g. connection GND and earth) may result in not-permissible voltages impairing or destroying the device or another device connected. page 6 HND-R106 K09/0422... - Page 7 Warning: Do not use these products as safety or emergency stop devices or in any other application where failure of the product could result in personal injury or material damage. Failure to comply with these instructions could result in death or serious injury and material damage. HND-R106 K09/0422 page 7...

The measurement is done with a common silver chloride electrode (reference system with 3-molar potassium chloride solution). The measured value can be directly displayed (mode mV) or converted to “reference system: standard hydrogen electrode” and temperature compensated at mode mVH. HND-R106 K09/0422 page 11... -

2. Get the rH value: Connect ORP electrode and set device to rH measuring mode. The main display shows the calculated rH value of the solution, the secondary display shows the prior measured pH value and the temperature alternatingly. page 12 HND-R106 K09/0422... -
Page 13: Ph Electrode
Electrodes have to be stored in a way that they are kept wet. An adequate solution is to store them with suitable protective cap filled with KCl 3 M. Please consider also the instructions in the electrode’s manual! HND-R106 K09/0422 page 13... -

(see below). When working with the standard or DIN-buffer series, the influences of buffer temperature are also compensated. If buffers are entered manually, make sure to enter the pH-values of the buffers at the relevant temperature to ensure optimum calibration of the device. page 14 HND-R106 K09/0422... - Page 15 Place electrode and temperature probe (if any) in the second buffer solution (e.g. for standard series this is: pH 4.0 or pH 10.0) and stir gently. As soon as the measured pH value got stable the next calibration step will be displayed. HND-R106 K09/0422 page 15...
