3 Handling Precautions
JMeter and sensor
zThe sensor is a consumable part. If it becomes damaged or its
performance deteriorates, replace it with a new one (the sensor can not
be repaired).
zDo not swing the meter and sensor by holding a strap.
zTo ensure the waterproof performance, confirm the followings when
attaching the sensor.
- The waterproofing gasket is clean and undamaged.
- The waterproofing gasket is seated properly in the groove with no
twisting or warping.
- The meter and sensor are not deformed.
zNeither the meter nor sensor is waterproof by itself.
The sensor must be securely mounted on the meter
before use.
zDo not drop the meter or apply excessive force to it.
zDo not leave the meter in areas of direct sunlight or high temperature/
humidity.
zDo not clean the meter with organic solvents.
zThe flat sensor is made of thin glass. Take care not to break it. If it is
damaged, remove the sensor avoiding injury and dispose of it in a
plastic bag.

5
zDo not measure samples such as the following, since they may
damage the sensor or shorten its life: Organic solvents, oils, adhesives,
cement, alcohols, concentrated acid (0 pH to 2 pH), concentrated
alkaline (12 pH to 14 pH) or surfactants.
zWhen using this product for the first time or after several days of
disuse, the sensor may be slow to respond. In this case, add some
drops of pH 7 standard solution to the sensor and wait a few hours
before use (there is no need to turn the power ON).
zFor some sample types (such as pure water), the measured value may
be unstable.
zA small amount of liquid or white powder may appear on the liquid
junction of the flat sensor. The appearance of this powder or solution is
normal. Simply rinse it off with water before use.
JBattery
zKeep batteries out of reach of children. If someone accidentally
swallows a battery, call a doctor immediately.
zDo not throw batteries in fire.
zDo not attempt to recharge batteries.
zThe provided batteries are intended for use in operation checking,
therefore their service life may be short.
zThe battery alarm icon lights up when the battery voltage is low.
Replace the batteries when the battery alarm icon lights up. The meter
power may not be turned ON/OFF when the battery voltage is low.
zReplace the 2 batteries at the same time.
JOthers
zWash off any calibration fluid that comes into contact with hands or
other exposed skin. If fluid gets in eyes, rinse them immediately and
see a doctor.

4 Basic Handling
4.1 Inserting/removing batteries
Note
zTurn OFF the meter before inserting/removing batteries.
zAlways replace both batteries at once. Do not use old and new
batteries together.
JInserting the batteries
1. Slide both batteries into the
battery case as shown.
Be sure to use two CR2032
batteries, and put them with the plus
sides (+) upwards.
JRemoving the batteries
1. Use a ball-point pen or other tool to pry
the batteries out from the clips as
shown.

4.2 Attaching/detaching the sensor
Note
zTurn OFF the meter before attaching/detaching the sensor.
zIf the meter is turned ON with the sensor detached, the battery
alarm may light up. In this case, turn OFF the meter and attach the
sensor, and then turn ON the meter again.
Note
zMake sure that the sensor tongue is outside the meter case.
If the tongue is inserted between the case and the connector of
the meter, it may damage the connector.
zWhen removing the sensor, do not let any water get inside the
meter. If some moisture remains on the waterproof gasket, wipe it
off carefully.
JAttaching the sensor
1. Confirm that the waterproofing gasket is
clean and undamaged.
2. Slide the sensor onto the meter so that
catch "A" on the back of the meter fits
into hole "a" on the sensor tongue as
shown.
Note
Be careful not to twist the waterproof gasket.
JDetaching the sensor
1. Lift the sensor tongue tip and slide the
sensor a little away from the meter.
2. Pull out the sensor all the way from the
meter.

4.3 Power ON/OFF
4.4 Storage
1. Clean the sensor with tap water and remove moisture on the sen-
sor and meter with soft cloth or paper.
Note
Do not push the flat sensor strongly. It may damage the sensor.
2. Close the light shield cover and the slide cap, then store the
meter.
JPower ON
1. Press and hold the ON/OFF switch for
over 2 seconds.
The power is turned ON, and the meter
model number is displayed on the LCD.
JPower OFF
1. Press and hold the ON/OFF switch for
over 2 seconds.
The power is turned OFF.

5Calibration
5.1 About calibration
JCalibration points
The available calibration points depend on the meter models.
zOne-point calibration at pH 7: B-711, B-712, B-713
zOne-point calibration at pH 4: B-712, B-713
zTwo-point calibration: B-712, B-713
“One-point calibration at pH 7” is set by default.
Refer to the instructions on page 19 for switching the calibration points (for
B-712 and B-713 only).
The calibration point setting and calibration result are saved after the meter
is turned OFF.
Tip
For B-712 and B-713, two-point calibration is recommended especially
if sample pH is outside 1 pH from the pH of the standard solution.
JPrecautions for calibration
zIf remains blinking and Err (error display)
appears, the calibration is failed.
Check that the standard solution pH is correct,
and perform calibration again after cleaning the
sensor well.
zIf the calibration is failed using correct standard solution(s), the sensor
may be deteriorated. Replace the sensor with new one (part No.:
3200459834).
zIn two-point calibration, confirm that the calibration operations are
completed respectively for pH 7 and pH 4.
The calibration operation for pH 4 can not start until the calibration for
pH 7 is completed, and the whole calibration sequence is not com-
pleted until the calibration for pH 4.

6 Measurement
6.1 Sample setting
The following 4-type sampling setting methods are available.
zDrop: for a small-amount sample
zImmersion: for a large-amount sample
zScooping: for sampling a part of a sample
zSampling sheet: for a sample containing tiny particles
Note
Although this product is waterproof, avoid immersing it completely.
If the product is accidentally dropped into water, take it out of water
and remove the moisture on it.
Tip
JDrop
1. Open the light shield cover and put some drops of sample on the
flat sensor to cover the entire flat sensor.
2. Close the light shield cover.
Try to use the provided sampling sheet B
for a minute sample.
Using this sheet, the entire flat sensor can
be covered with only 50 PL to 100 PL
sample.
zNote that a reaction between a
sample and the sampling sheet B
may affect the measured value.
zHandle the sampling sheet B with tweezers to minimize possible
contamination.
zMake sure to close the light shield cover during measurement to
minimize possible sample evaporation.
