⚫Please read the specifications before using the instrument.
⚫The instrument must be sent to metrological service or other departments that
are qualified to check for checking after being used for one year, and only
those qualified ones can be used again.
⚫The expiration date of the electrode should be referred to the “Electrode
Instruction Manual”. Its performance will be affected after the expiration date
whether it’s used or not and should be replaced in time.

The Meter is composed of an electric unit and a probe system. The probe system
contains conductive probe and ATC probe. The measurement probe is platinum-black
conductive probe and the temperature sensor isATC probe (Refer to the final packing list for
contents actually shipped). User may select another conductive probe with an appropriate
cell constant for the expected conductivity of the samples to be measured.)

1.3.1 Installation of the meter
⚫Take out electrode holder base
⚫Insert the electrode holder into the base
⚫Put the electrodes into the electrode holder
⚫Put the Conductive probe into Cond socket
⚫Put theATC probe into the Temp. Socket
⚫Rinse the electrodes with DI water and then pull into sample
1.3.2 Installation of the power adapter
A universal power adapter is included with the 910/9. The power adapter operates at
100–240 V/AC, 50/60 Hz. The output is 9V, 0.8 A.
User should connect the power adapter with the instrument at one side and power
supply at the other side.
Caution:
The power adapter only applies to this instrument; please don't use it to
other instrument. Do not use any other power adapters with the 910/9.

1.3.3 Installation of the USB communication cable
While using the data collection software, link the instrument and PC with USB
communication cable.After installing the USB driver, it is ready to communication.
Caution:
Please install USB driver on PC before using USB communication function.
1.3.4 Installation of the printer line(optional)
For printing function, customized printing line should be used.Link instrument and
printer(RS232 port) with printer line, set the baud rate of printer to 9600bps, then it’s ready
to print.
Caution:
1. To avoid unnecessary loss, please power off the instrument and printer before
connecting to the printer.
2. The baud rate of the instrument is always 9600bps, default setting is 8 data bits, 1
start bit, 1 stop bit, no parity.
2 Operation guide
2.1 Introduction
Please make sure to read the installation guide and operation guide before using the
meter.
Note following problems before using:
⚫The use of non-original power adapter can cause unnecessary safety problems.
⚫Ensure a good grounding.
⚫Prevent corrosive gas invasion.
⚫Keep the meter interface clean and dry, avoid contacting with acid, alkali, salt solution.
⚫Be careful not to use brute force when installing the electrode. Check the marking of the
electrode plug and insert it carefully.
⚫This instrument is available to long-term stability. After sample test, the
electrode should be immersed in distilled water. If the testing interval is longer
than 6 hours or for long-term storage, it is suggested to be cleaned and stored
in empty protection bottles.
