1. INTRODUCTION

Thank you for selecting the Waterproof PC 10 portable meter. The meter is a microprocessor-

based instrument that measures pH, conductivity, and temperature with just one probe. This

meter has many user-friendly features – all of which are completely accessible through the

water-resistant membrane keypad.

Your meter includes 4 “AAA” batteries and a combination pH / conductivity / temperature

probe with 3-meter submersible cable. 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.

x The primary display shows the measured pH or conductivity (μS or mS)

reading.

x The secondary display shows the temperature in °C.

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

See Figure 2.

2.2. Keypad

The large membrane keypad makes the instrument easy to use. Each button, when pressed,

has a corresponding graphic indicator on the LCD. See Figure 3.

Key Function

ON/OFF Powers on and shuts off the meter. The meter powers on in the mode it was

shut off in. For example, if you shut the meter off in Conductivity measurement
mode, the meter will be in Conductivity measurement mode when you switch
the meter on.

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

measurement mode. To release, press HOLD again.

MODE Selects the measurement parameter (conductivity or pH). Press MODE to

toggle between pH and Conductivity mode.

CAL/MEAS Toggles user between Calibration and Measurement mode.

If you were in Conductivity Measurement mode, press CAL/MEAS to enter
Conductivity Calibration mode.

If you were in pH Measurement mode, press CAL/MEAS to enter pH
Calibration mode.

NOTE: Temperature calibration is accessible from pH Calibration mode; see

pages 10 for instructions.

ENTER Press to confirm your calibration values in Calibration mode.

S / T Scrolls values up and down in Calibration mode.

In pH mode, S / T scrolls through the auto buffer values 4.00, 7.00 and

10.00.
In Conductivity and Temperature Calibration mode,S / T lets you increase

or decrease the calibration value.

3.2 Connecting the Probe

The Waterproof PC 10 meter uses a special combination pH / Conductivity / Temperature

probe. The probe cable has a notched 6-pin connector to attach the probe to the meter.

NOTE: Do not substitute other probes or electrodes. For replacement probe, see

the “Accessories” section, page 21-23.

NOTE: Keep connector dry and clean. Do not touch connector with soiled hands.

To connect the pH / Conductivity / Temperature probe:

1. Line up the notch and 6 pins of the meter’s connector with the holes in the probe’s

connector. Push down and screw the metal sleeve to lock the probe connector into

place. See Figure 5.

2. To remove probe, unscrew the metal sleeve and slide up the probe connector. While

holding onto metal sleeve, pull probe away from the meter.

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