Zero-setting and Measurement
ZERO Setting with the water used for the sample dilution.
【Caution】
◇Zero-set the instrument at the beginning of each day before use as well as after replacing the batteries.
◇Let water on the sensor acclimate to the temperature of the instrument before zero-setting.
◇When “AAA”is displayed, wipe the sensor clean, apply water, and press the ZERO button again.
1. Wipe the sensor clean and apply about
0.6mL of water used for dilution.
2. Press the ZERO button while the
water is on the sensor.
3. Zero-setting is complete
when “000”blinks twice and then
stops.
Proceed to measurement.
Wipe the sensor clean with tissue
paper.
Press the ZERO button (with nothing on the sensor).⇒Clear the zero setting.
Measurement
1. Wipe the sensor clean and
apply about 0.6mL of the sample.
2. Press the START
button
3. After “---”appears, the
measurement and the
sensor temperature are
displayed.
【Caution】
◇This instrument displays the concentration of peracetic acidin water as a ppm of total volume.
◇Do not use metal tools to apply samples on the sensor as they may scratch the sensor.
◇Initial measurements may fluctuate with hot or cold samples. Wait for the instrument to acclimate to the sample temperature,
approximately 20 seconds, to press the START button. Alternatively, press the START button multiple times until
measurements become stable.
◇Do not splash water above 50℃. The plastic may warp, which may compromise the water resistance.
◇The displayed temperature is that of the sensor and may not necessarily match the temperature of the sample.

Replacing the Batteries
【Caution】
◇Fasten the battery compartment cover tightly to prevent water ingress or poor connection, which will cause erroneous
measurements. Push the cover in firmly and turn.
◇When the O-ring on the cover is dirty or damaged, the water resistance may be compromised.
◇When the battery icon indicates the low power level ( ), replace both batteries with a brand new set of AAA alkaline batteries
(1.5V).
◇Static images may occasionally appear on LCD. Such retained pixel charges do not indicate a faulty display, consume the battery
power, or affect the instrument’s performance in any way.
◇Check the expiration dates on batteries before purchase.
◇Zero-set the instrument after the batteries are replaced.
1. Insert a coin in the
groove on the battery
compartment cover. Turn
the coin counterclockwise
to remove the cover.
2. Insert batteries,
observing the correct
polarity.
3. Align the cover
and push it down.
4. Close the battery compartment cover by
pushing the cover in with a coin in the groove
and turning it clockwise until it stops.
*Turning excessively may cause malfunction.
