1 INTRODUCTION

Thank you for selecting Eutech Instruments standard CyberScan pH 10/100 meter. These

meters are microprocessor-based instrument and are designed to be handy, capable of

allowing one-hand operation. Each has a large custom dual LCD for clear and easy reading. It

is a unique and intelligent instrument that has the capability to cater to the preferences of the

discerning individual.

Both meters have many user-friendly features – all of which are completely accessible through

the splash-proof membrane keypad. Your meter includes a temperature probe (EC-PHTEM-

01P), electrode holder, built-in meter stand and batteries. Eutech Instruments offer a wide

selection of pH and ORP electrodes. Refer to “Accessories” section for more information.

The basic model is the CyberScan pH 10 which is capable of measuring pH, Temperature,

and millivolt (mV).

The deluxe model is the CyberScan pH 100 which measures pH, Temperature, millivolt (mV)

and relative millivolt (Rel mV). It has many advanced features and allows you to customize the

meter settings. It also has a RS232C port that allows the meter to be connected to a computer

or a printer via a cable for transferring data.

For power requirement, you can either use 4 AAA-sized batteries or an AC/DC power adapter

(sold separately).

Please read this manual thoroughly before operating your meter.

2 DISPLAY AND KEYPAD FUNCTIONS

2.1 Display

The LCD has a primary and secondary display.

•The primary display shows the measured pH or ORP values.

•The secondary display shows the measured temperature.

The display also shows error messages, keypad functions and program functions.

2.2 Keypad

A large membrane keypad with tactile feedback makes the instrument easy to use. Each

button, when pressed, has a corresponding graphic indicator on the LCD (Figure 1). Some

buttons have several functions depending on its mode of operation.

Key Function

ON/OFF Powers on and shuts off the meter. The meter will start in pH measurement mode.

HOLD Freezes the measured reading. To activate, press HOLD while in measurement

mode. To release, press HOLD again.

MODE Selects the measurement parameter. Default is pH measurement. Press MODE to

toggle between pH, Temperature, Rel mV (only pH 100), mV, & back to pH

measurement mode.

CAL/MEAS Toggles between Calibration and Measurement mode.

1. If you are in pH measurement mode, press CAL/MEAS to enter pH calibration

mode.

2. If you are in temperature measurement mode, press CAL/MEAS to enter

temperature calibration mode.

3. If you are in Rel mV (only in pH 100) measurement mode, press CAL/MEAS to

enter Rel mV measurement calibration mode.

While in SETup (only in pH 100) menu, pressing CAL/MEAS takes you out and into

the measurement mode.

CON CONfirm function: Press to confirm values in Calibration mode and to confirm

selections in SETup mode.

"key to adjust

temperature values in °C.

3. If you are in Rel mV (only in pH 100) calibration mode, press !

"key to

adjust mV values.

In SETUP mode (only in pH 100):

Press !

"key to scroll through options in each SETup programs.

MI / MR (only

in pH 100)In measurement mode (pH, Rel mV or mV) press MI (memory input) to store values

with its corresponding temperature values in the memory. Press MR (memory recall)

to retrieve data from memory.

(only in pH

100)

Allows you to print current measurement to either the printer or the computer.

SETUP (only

in pH 100)Takes you into the SETUP mode. This mode lets you customize meter preference

and defaults, view calibration, electrode offset data, clear memory, change pH

resolution, and communication protocol setting.

3 PREPARATION

3.1 Inserting the Batteries

The CyberScan is packaged with 4 “AAA” alkaline batteries required for operation. To insert

the batteries into the CyberScan, follow the procedure outlined below.

1. Use a Phillips Head screwdriver, remove the two screws (Figure 4) with the hinge closed.

2. Remove the battery cover. Note the polarity and insert the batteries into the battery

compartment correctly (Figure 5).

3. Replace the battery cover into its position and screw back using the two screws removed

earlier.

Your CyberScan hand-held meter is now ready for operation.

removing 2 screws

3.2 Connecting the pH Electrode, Temperature Probe & Electrode Holder

The Eutech Instruments CyberScan pH 10/100 meter uses any standard pH, ORP, or Ion

Selective Electrode (ISE) with a BNC connector. For Automatic Temperature Compensation

(ATC), this meter requires a temperature probe with a phono-jack connector.

NOTE: It is important that water does not get onto the BNC connector. Also avoid touching the

connector with soiled hands.

3.2.1 To connect pH, ORP or ISE electrode

1. Slide the electrode connector of the

electrode over the BNC connector

socket on the meter.

2. Make sure the slots of the connector are

in line with the posts of the socket.

3. Slide the BNC connector of the probe

over (Figure 6).

4. Rotate and push connector clockwise

until it locks.

5. To remove electrode, push and rotate

the connector anti-clockwise.

6. While holding onto the metal part of

the connector, pull it away from the meter.

7. Be careful not to use excessive force.

CAUTION: Do not pull on the probe cord or the probe wires might disconnect.

Refer to “Accessories” section for information on temperature probe and other electrodes.

3.2.2 To connect the temperature probe:

The temperature probe (provided) uses a phono

jack to connect with the socket on the CyberScan.

Insert the jack fully into the socket (Figure 7).
