Instruction Manual pH Simulator

1 Introduction

Thank you for selecting our palm top pH and mV simulator. This simulator is designed to be handy,
capable of allowing one hand operation.

Your simulator has a user friendly feature of push button operation for selection of pH and mV
values which are accessible through the 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.

2 Display and Keypad Function

2.1 Display

The display consists of 16 sets of labeled LED for the selection of pH and mV values.
The display also includes the low battery indicator LED at the bottom left hand corner.

1.00 – 1.00 pH Value 10.01 – 10.01 pH Value 1800 – 1800 mV Value -900 - -900 mV Value

1.68 – 1.68 pH Value 12.45 – 12.45 pH Value 900 – 900 mV Value -1800 - -1800 mV Value

4.01 – 4.01 pH Value 6.86 – 6.86 pH Value 390 – 390 mV Value 4 HI Z – 4.01 High Impedance pH value

7.00 – 7.00 pH Value 9.18 – 9.18 pH Value -390 - -390 mV Value 10 HI Z –10.01 High Impedance pH value

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.

Battery Replacement

A low battery LED alerts you when battery power is running low. See Figure 5. Replace with the

same type as recommended by the manufacturer.

Caution: Power off the simulator when changing battery.

3.4 Connecting the BNC cable to simulator

1. Insert the BNC connector of the cable over the BNC connector 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.
