TPS WP-Sim User manual

Congratulations !
The WP-Sim is a complete pH, ORP, Conductivity, TDS and
Temperature simulator for TPS instruments. The WP-Sim provides an
indispensable tool for checking the operation of instruments without
sending them to the factory for service.
The manual is divided into the following sections:
1. Table of Contents
Each major section of the handbook is clearly listed. Sub-sections
have also been included to enable you to find the information you
need at a glance.
2. Introduction
The introduction has a diagram and explanation of the display and
controls of the WP-Sim. It also contains a full listing of all of the items
that you should have received with your WP-Sim. Please take the
time to read this section, as it explains some of items that are
mentioned in subsequent sections.
3. Main Section
The main section of the handbook provides complete details for
operation of the WP-Sim.

pH / mV Output Selector
Used to select one of a range of pH and Millivolt values. The Function
switch must be set to ON or Impedance for the pH/mV output to be
active. See sections 2and 3.
Conductivity / TDS Output Selector
Used to select one of a range of Conductivity and TDS values. The
values are simulated by a precision resistor network, so the Function
switch can be left in the OFF position for these tests. See section 4.
Function Switch
Used to select ON / OFF, Impedance (section 7) or Battery Test
(section 8).
pH / mV Output Connector
All pH and Millivolt signals are output through this connector.
Conductivity / TDS / Temperature Output Connector
All Conductivity, TDS and Temperature signals are output through
this connector.

2. Simulating pH Values
1. Obtain the correct pH / mV output cable for the instrument under test.
2. Connect one end of the pH / mV output cable to the WP-Sim and the
other end to the instrument under test, as per the example diagram
below…
3. Switch the WP-Sim Function switch to ON. Switch the instrument
under test on and select pH mode. See the instrument’s handbook if
necessary.
4. Use the pH / mV selector to output any of the 5 simulated pH values.
The readout of the instrument under test should approximately
correspond to the simulated pH value selected on the WP-Sim.
Variations are possible due to the current temperature and calibration
settings of the instrument under test.
Please note that the simulated values are for 25 OC.

3. Simulating Millivolt Values
1. Obtain the correct pH / mV output cable for the instrument under test.
2. Connect one end of the pH / mV output cable to the WP-Sim and the
other end to the instrument under test, as per the example diagram
below…
3. Switch the WP-Sim Function switch to ON. Switch the instrument
under test on and select Millivolt mode. See the instrument’s
handbook if necessary.
4. Switch the pH / mV selector to 650 mV. The readout of the instrument
under test should be approximately 650 mV. Variations are possible
due to the current calibration settings of the instrument under test.

4. Simulating Conductivity and TDS Values
1. Obtain the correct Conductivity / TDS output cable for the instrument
under test.
2. Connect one end of the Conductivity / TDS output cable to the
WP-Sim and the other end to the instrument under test, as per the
example diagram below…
3. The WP-Sim does not need to be switched on for Conductivity or
TDS output. Switch the instrument under test on and select
Conductivity or TDS mode as required. See the instrument’s
handbook if necessary.
4. Use the Conductivity / TDS selector to output any of the 4 simulated
Conductivity or 2 simulated TDS values. The readout of the
instrument under test should approximately correspond to the
simulated Conductivity or TDS value selected on the WP-Sim.
Variations are possible due to the current temperature and calibration
settings of the instrument under test.
Please note that the simulated values are for 25 OC.
