Introduction

Thank you for purchasing the HIOKI “Model 9742-10 OPTICAL
SENSOR.” To obtain maximum performance from the device,
please read this manual first, and keep it handy for future refer­ence.

Overview

The 9742-10 is an optical sensor for the 3664 OPTICAL POW­ER METER capable of measuring up to 50 mW in the range of
wavelengths from 320 to 1100 nm.

Inspection and Maintenance

Initial Inspection

When you receive the device, inspect it carefully to ensure that
no damage occurred during shipping. If damage is evident, or if
it fails to operate according to the specifications, contact your
dealer or Hioki representative.

Preliminary Checks

• Before using the device the first time, verify that it operates
normally to ensure that the no damage occurred during stor­age or shipping. If you find any damage, contact your dealer
or Hioki representative.

• Before using the device, make sure that the insulation on the
cables is undamaged and that no bare conductors are
improperly exposed. Using the device in such conditions
could cause an electric shock, so contact your dealer or Hioki
representative for repair.

Maintenance and Service

• To clean the device, wipe it gently with a soft cloth moistened
with water or mild detergent. Never use solvents such as
benzene, alcohol, acetone, ether, ketones, thinners or gaso­line, as they can deform and discolor the case.

• With the exception of ethyl alcohol, avoid using organic sol­vents to clean the detector window. These solvents can dam­age the detector window.

• If the device seems to be malfunctioning, contact your dealer
or Hioki representative.

• Pack the device so that it will not sustain damage during
shipping, and include a description of existing damage. We
cannot accept responsibility for damage incurred during ship­ping.

This device is designed to comply with IEC 61010 Safety
Standards, and has been thoroughly tested for safety prior to
shipment. However, mishandling during use could result in
injury or death, as well as damage to the device. Be certain
that you understand the instructions and precautions in the
manual before use. We disclaim any responsibility for acci­dents or injuries not resulting directly from device defects.

Safety Symbol

In the manual, the symbol indicates particularly important
information that the user should read before using the device.

The symbol printed on the device indicates that the user
should refer to a corresponding topic in the manual (marked

with the symbol) before using the relevant function.

The following symbols in this manual indicate the relative impor­tance of cautions and warnings.

Indicates that incorrect operation presents an extreme
hazard that could result in serious injury or death to the
user.

Indicates that incorrect operation presents a possibility
of injury to the user or damage to the device.

Indicates advisory items related to performance or cor­rect operation of the

device

.

Operating Precautions

Follow these precautions to ensure safe operation and to obtain
the full benefits of the various functions.

• To prevent malfunctions in the 3664 or the optical sensor,
avoid connecting or disconnecting the optical sensor con­nector while power for the 3664 is ON.

• To avoid damaging the optical sensor and to ensure accu­rate measurements, avoid dropping or applying any physical
shock to the optical sensor.

• Avoid touching the detector window with your bare hands.
The detector window must be clean for the sensor to meet
the specified performance parameters.

• Avoid scratching the detector window with sharp or pointed
objects (e.g., the tips of tweezers) or against hard surfaces.
Damage to the detector window may prevent the sensor
from meeting specified performance parameters.

• To avoid breaking the cables, do not bend or pull them.

• To avoid broken wires, always grasp the plug to disconnect
the optical sensor connector. Avoid pulling on the cable it­self.

• Excessive power input may damage the sensor. Avoid ex­posing the sensor to light whose intensity exceeds specifica­tions.

• Avoid exposing the sensor to intense beams that lie beyond
the range in which it can render accurate results. In addition
to inaccurate results, doing so may damage the sensor.

• Make sure no stress is applied to the repeater cable between
the sensor main unit and its light-receiving element.

• This device is not designed to be entirely water- or dust­proof. Do not use it in an especially dusty environment, nor
where it might be splashed with liquid. This may cause dam­age.

To ensure accurate measurements, make sure the detector win­dow is free of dust, stains, and any damage.

2. Place the 9742-10 optical sen­sor with the arrow side facing up
and insert into the optical sensor
connector of the 3664.

3.Turn on power for the 3664.

4.Remove the cover of the optical
sensor.

5.Irradiate with light.

• Always grasp the connector with the arrow to connect or dis­connect the optical sensor. You must grasp the connector to
disconnect the sensor.

• To prevent dust accumulation, stains, and damage, cover the
detector window with the sensor cover when the sensor is
not in use.

• Take care to avoid misplacing the sensor cover.

• Note the correct orientation of the sensor cover. The HIOKI
logo should face in the direction indicated in the diagram
above.

Cleaning the detector window

With the exception of ethyl alcohol, avoid using organic sol­vents to clean the detector window. These solvents can dam­age the detector window.

1.Open the sensor cover.

2.Wipe the detector window of the sensor using lens cleaning
paper or other lint-free material.
If lint remains on the detector window, blow off with an optical
lens airbrush.
If the detector window is soiled, fluff the tip of a cotton swab.
Moisten the cotton tip in ethyl alcohol and wipe the surface.
