Preface
This manual serves to explain the use of the pH Simulator.
This manual functions in two ways: first as a step by step guide to help you operate the
meter; second, it serves as a handy reference guide.
Eutech Instruments/Oakton Instruments will not accept any responsibility for damage or
malfunction to the meter caused by improper use of the instrument.
The information presented in this manual is subject to change without notice as
improvements are made, and does not represent a commitment on the part of Eutech

Instruction Manual pH Simulator
1 Introduction
Thank you for selecting our pH/mV simulator handheld. This simulator is designed for
convenient one-hand operation.
Your simulator features user-friendly push-button operation for selection of pH and mV
values on a splash-proof membrane keypad. It also has a large LED display for easy
reading.
Your simulator includes a 1 meter BNC to BNC cable and 4 AAA batteries.
This manual provides a step-by-step guide to operate the simulator.

3 Preparation
3.1 Inserting & Removing Rubber Boot
1. To remove simulator from rubber boot, push out from the bottom edges of
simulator until it is completely out of boot. Ensure that the BNC cables are not
connected.
2. To insert simulator into rubber boot, slide in from the top of meter before
pushing the bottom edges of simulator down to set it into position. Lift up the
stand at the back of simulator for bench top applications if necessary.

3.2 Inserting the Batteries
The battery compartment is found at the back of instrument as shown in Figure 4. To
open the battery compartment:
1. Push in the direction of arrow and lift up the cover.
2. Note the polarity of battery before inserting into position.
3. After replacement, place cover back and press down until it locks tight.

3.3 Battery Replacement
A low battery LED alerts you when battery power is running low. See Figure 5. Replace
with the same type as recommended.

3.4 Connecting the BNC cable to simulator
1. Insert the BNC connector of the cable over the BNC socket on the simulator.
2. Make sure the slots of the connector are in line with the posts of the socket.
3. Slide the BNC connector of the cable over the socket and rotate the
connector clockwise until it locks.
4. To remove cable, push and rotate the connector counterclockwise.
5. While holding onto the metal part of the connector, pull it away from the
simulator.
6. Be careful not to use excessive force.
CAUTION: Do not pull on the cable cord or the cable wires might disconnect.

4 Operating Procedure
The simulator is designed to test the accuracy of your pH/ORP meters. It includes the
simulation values for the USA and NIST buffer set standards and the simulation
performance of an electrode in pH 4.01 and pH 10.01 buffers (4 Hi Z & 10 Hi Z). This
High Impedance pH simulation is useful for testing suspected leakage problems of your
pH/ORP meters.
1. Connect the BNC end connector of your simulator to the pH/ORP meter.
2. Switch the simulator on by pressing the ON/OFF button. The ‘7.00’ LED will
light up indicating that the pH 7.00 simulation value has been selected.
Note: The simulator will always be in the pH 7.00 selection every time it is turned
on.
3. Press the ▲ and ▼ key to scroll through the value selection on the LED
display. The LED will light up according to your preferred selection.
4. Select the desired simulation value indicated by the LED light up display.
