OPERATING PROCEDURE:

ACCESSOR ES

Upon receiving the shipment, inspect the container and equipment for any signs of damage.

Verify that you have received all the items listed below:

Meter, Buffer Solution pH 4 & 7, Soa ing Solution, Lanyard, Battery (installed), Instruction

Manual and Carrying Case. Optional: ORP electrode, Buffer pH 10.01

PREPARAT ON

1. Remove the protective cap and unscrew the soaking solution from the meter to rinse the

electrode with clean water and wipe it dry. Don't leak soaking solution from bottle and place

the protective cap back on the bottle at the end of usage.

2. Press button to turn the meter power on.

CAL BRAT ON

＜pH＞

1. Make sure the sensor is pH electrode or check the icon appears in the LCD display.

2. Dip the electrode into the buffer solution pH 7. Stir gently and wait until the display is

stabilized. Press and hold button to enter calibration mode until the icon CAL appears on

the display, and flashes 7.00. When the display stops flashing and indicates “SA”, then “End”

while calibration is ending and returns to measurement mode.

3. Rinse the electrode with clean water and wipe it dry. Dip the electrode into the buffer

solution pH 4. Stir gently and wait until the display is stabilized. Press and hold button

to enter the calibration mode until the icon CAL appears on the display, and then flash 4.00.

When the display stops flashing and indicates “%” (percentage of slope), it will then display

“SA”, then “End” while calibration is ending, and then return to measurement mode.

4. After slope calibration pH 4 or pH 10, the display will indicate percentage of slope (PTS) to

show the status of electrode. f the PTS is below 70% or above 130%, the electrode must be

replaced. A slope of 100% is ideal.

Note: (1) con “SA” will not appear if the calibration fails.

(2) When doing a 2 or 3 point calibration, Calibrate with buffer pH 7 first, and then

follow with buffer pH 4 or pH 10.

MEASUREMENT

＜pH＞

1. After calibration, rinse the electrode with clean water and wipe it dry.

Dip the electrode into sample solution to be measured. Stir gently and wait until a stable

reading can be obtained.

DPH7011 Manual FINAL-8-15-08:Layout 1 8/15/08 12:10 PM Pa e 5

＜ORP＞

1. nsert ORP electrode and the icon will show on the LCD display automatically.

2. Calibration is not necessary for ORP. t could be tested with a specific ORP solution to check

if electrode is good or bad.

3. Rinse the electrode with clean water and wipe it dry. Dip the electrode into sample solution

to be measured. Stir gently and wait until a stable reading can be obtained.

Note: (1) “_ _ _ _” will appear in the display when it is over the measuring range.

(2) After measurement, rinse the electrode with clean water. Replace the protective cap

and soaking bottle. The soaking bottle should always be kept wet by adding soaking

solution.

FUNCT ONS MODE

1. Press button to enter the Hold function mode. The icon HOLD will appear and the

reading value in the display can be locked. Return to Measurement mode while pressing the

button again.

2. Press and hold button to enter the measuring Maximum and Minimum function mode.

Hold button until a flashing icon of MAX and M N appears in the display. The value of

maximum and minimum will appear in the display while pressing the button lightly. To exit

this mode, press and hold button until icon MAX and M N disappear, and returns to

Measurement mode.

3. Press and hold button to change °F or °C.

Note: (1) The display can not auto shut off under the status of MAX/M N mode.

(2) Change a new battery when the battery indicator is flashing.

MAINTENANCE:

BATTERY REPLACEMENT

1. Loosen the screw with a screwdriver on the battery compartment cap.

2. Replace with fresh 4 “AAA” batteries and note polarity.

3. Replace the battery compartment cap and tighten the screw.

Note: (1) Be sure batteries are in the correct position by polarity.

(2) Don’t loosen the O-ring which has been mounted on cap.

ELECTRODE REPLACEMENT

1. Unscrew the electrode collar counterclockwise and remove it completely.

2. Pull the electrode module out from the tester.

3. Plug in a new electrode module into the tester socket carefully.

4. Place and tighten the electrode collar to make a good seal.
