6. Maintenance

6-1. Storage and treatment of the sensor

The sensor is the most sensitive part of the Chloride-Meter. The following directions for care

should be observed to secure the reliability of the test results when re-using the sensor as

well as to ensure long-term use.

(1) Treatment of the sensor while measuring

- In case you have to stop the test temporarily, immerse the electrode in cleaning solution.

- Always keep the internal solution of the sensor at least 2/3 full.

(2) Storage

- When the sensor is not in use for more than one day, plug refill hole with cap and store

the sensor after put on protection cap.

(3) Re-using the sensor

Immerse the sensor in cleaning solution for an hour before you use.

6-2. Storage of meter

Item

Condition

Ambient Temperature

-5 ~ 50

Avoid

places

where

sudden

changes

in

temperature coour which could cause freezing

or condensation.

Storing Temperature

-5 ~ 50

Relative Humidity

Environment

The place should be away from direct sunlight and free from

dust, corrosive gas, inflammable gases oil mists, steam, dripping

water or vibration, salty environments should be preferably be

avoided.

7. Warranty and A/S

7-1. Quality certification

(1) A quality certificate for this meter is included in the box.

(2) The warranty is valid for one year from the day of purchase. It covers defective parts of

the sensor which occurs within the warranty period. This warranty extends only to the original

retail purchaser.

However, it does not cover the misuse, abuse, negligence, modification of the sensor, or any

defects caused by a natural disaster. After the applicable period you must pay for A/S.
