INTRODUCTION

This user’s manual describes instructions for handling of the PUS400G ultrasonic oscillator, including

procedures for installation, operation, inspection and maintenance. Also, information necessary for

you to further understand the product is described as required.

For handling of an ultrasonic vibrator for use together with this apparatus, refer to the user’s manual

attached to the instrument with the ultrasonic vibrator built in.

In continuous water quality measurement, pollutive components sticking to the sensor of a water qual-

ity meter is one of the causes of inaccurate measuring results. Therefore, cleaning of the sensor is an

indispensable maintenance item for a lot of water quality meters.

Ultrasonic cleaning is one of methods for cleaning sensors. The major strong point of ultrasonic clean-

ing is that you can continuously perform it while making measurement. Ultrasonic cleaning has clean-

ing effect on most of pollutive components. Water quality meters mean pH or ORP meter.

The PUS400G ultrasonic oscillator is an apparatus for supplying an ultrasonic vibrator, built in a water

quality meter, with high-frequency energy.

Below is the description of what you should do before use of the apparatus and what you should un-

derstand before reading this instruction manual.

Specication Check

Unpack your ultrasonic oscillator with care, and check for any damage that may be caused during

transport.

The PUS400G ultrasonic oscillator is fabricated to the customer

specications. For precautionary purposes, check to see that your

ultrasonic oscillator is in accordance with your specications, and

that there is no missing accessory. Use the model codes indicated

on the nameplate to check the specications of your ultrasonic os-

cillators. For the meaning of the model codes, refer to Section 1.2.

Location of Nameplate: Panel inside apparatus.

Precautions Which Must Be Taken when Actuating PUS400G Ultrasonic Oscillator during

Inspection

NOTE

When actuating the PUS400G ultrasonic oscillator, be sure to connect the ultrasonic vibrator (under

load, that is, immersed in uid) as under normal operating conditions. Operating the ultrasonic oscil-

lator solely (or, with the ultrasonic vibrator under no load connected) may cause some electric parts to

be abnormally heated. This is unfavorable in terms of the life of the ultrasonic oscillator.

1. Overview

The PUS400G ultrasonic oscillator is an apparatus that composes an ultrasonic cleaner together with

an ultrasonic piezoelectric transducer (vibrator). The PUS400G supplies the ultrasonic vibrator with

operating power via a cable.

The ultrasonic vibrator to be combined with the PUS400G is a vibrator mode of lead zirconate-

titanate-based piezoelectric ceramics.

The ultrasonic vibrator is built in the sensor holder of the pH meter.
