Information III
Safety Precautions
Be sure to read and follow these instructions !
The Model 136S Conductivity Meters may only be opened
to change the batteries outside hazardous areas. If repairs
are necessary, the meter must be sent in to the factory.
Never operate the remote interface or printer within haz-
ardous areas.
When using the meter in hazardous areas, watch for elec-
trostatic charges! For example, never wipe off the meter
with a dry cloth. Observe the relevant regulations concern-
ing ESD.
Whenever it is likely that the protection has been impaired, the meter shall
be made inoperative and secured against unintended operation.
The protection is likely to be impaired if, for example:
❏the meter shows visible damage
❏the meter fails to perform the intended measurements
❏after prolonged storage at temperatures above 70 °C
❏after severe transport stresses
Before recommissioning the meter, a professional routine test according to
EN 61 010-1 shall be performed. This test should be carried out at our fac-
tory.

Short Description of Meters
❏The Models 135A and 136S measure conductivity, sali-
nity, TDS and temperature in industry, the environment,
food processing and waste-water treatment.
❏Operation of the Model 136S is also permitted in Zone 1
hazardous areas.
❏The meters meet the European EMC regulations
(89-336-EEC) and the recommendations of NAMUR
NE 21.
❏The meters are IP 66 protected to EN 60 529.
Warning
Models 135A and 136S 2
❏Temperature compensation is automatic with a conducti-
vity probe with integral temperature sensor or a sepa-
rate ATC probe, or the temperature may be manually
entered.
❏Calibration can be carried out by directly entering the
cell constants, by calibrating with Thermo Orion Con-
ductivity Standards, or with any other buffer solutions.
❏The data log records up to 100 measured values with
the temperature, date and time. Recording takes place
either manually, interval or event-controlled.
❏To minimize battery consumption, the meter switches off
after either one or twelve hours when it is not operated.
❏Only three alkaline AA batteries are required for uninter-
rupted operation for approx. 1,000 hours.
❏PC software allows complete remote control of the me-
ter via PC. All measured values and parameters can be
read out and easily processed further (e.g. using Micro-
soft Excel).
❏Measured values and GLPdoctcan also be sent di-
rectly to a printer via the serial interface.
Never use the remote interface to PC or printer in hazard-
ous areas!

Pressing the power key switches the meter on or off.
After switching on, the meter automatically performs a
self-test and checks for the presence of a temperature
probe. Then it goes into the measuring mode.
Pressing the meas key returns the meter to the measur-
ing mode from any function. Pressing the meas key in the
measuring mode displays the following parameters:
Cond measuring mode: temperature compensation
tdS measuring mode: TDS factor
You can also power the meter up using the meas key.
However, only an abbreviated self-test is performed.
Pressing the cal key starts calibration.
