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.
• The primary display shows the measured pH or conductivity (µS or mS)
reading.
• 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.
/ Scrolls values up and down in Calibration mode.
In pH mode, / scrolls through the auto buffer values 4.00, 7.00 and
10.00.
In Conductivity and Temperature Calibration mode, / lets you increase
or decrease the calibration value.

3. PREPARATION
3.1 Inserting the Batteries
The meter is packaged with 4 “AAA” alkaline batteries required for operation. To insert the
batteries into the meter, follow the procedure outlined below.
1. Use a Philips screwdriver to remove the two screws holding the battery cover. See Figure
6 below.
2. Remove battery cover.
3. Insert batteries. Follow the diagram inside the cover for correct polarity.
4. Replace the battery cover into its original position using the two screws removed earlier.

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.

4. CALIBRATION
4.1. Important Information on Meter Calibration
When you recalibrate your meter, old pH and conductivity calibration data are replaced on a
point by point basis. For example, if you previously calibrated your meter at pH 4.0, 7.0, and
10.0, and you recalibrate at pH 7.0, the meter retains the old calibration data at pH 4.0 and pH
10.0.
To completely recalibrate your meter, or when you use a replacement probe, it is best to set
the meter to its factory defaults and recalibrate the meter at all points.
To reset the meter to its factory defaults:
1. While in Measurement mode, press
CAL/MEAS and hold for 3 seconds.
2. The meter will prompt RST in the lower display
and CAL in the upper display. See Figure 6.
3. Press ENTER to reset your meter to its factory
defaults. If you do not want to erase existing
calibration data, press CAL/MEAS to escape
this mode.
For information on how to calibrate your meter:
See Section 4.3 on page 8 for Temperature calibration.
See Section 4.4 on pages 10 for pH calibration.
See Section 4.5 on pages 12 for conductivity calibration.
