__________________________________________________ Safety symbols This symbol is affixed to locations on the equipment where the operator should consult corresponding topics in this manual (which are also marked with this symbol) before using relevant functions of the equipment. In the manual, this mark indicates explanations which it is particularly important that the user read before using the equipment.
Page 42
__________________________________________________ Accuracy The specifications in this manual include figures for "measurement accuracy" when referring to digital measuring instruments, and for "measurement tolerance" when referring to analog instruments. f.s. (maximum display or scale value, or length of scale) Signifies the maximum display (scale) value or the length of the scale (in cases where the scale consists of unequal increments or where the maximum value cannot be defined).
__________________________________________________ Notes on Use CAUTION The detector and display of this unit can be separated. In order to prevent damage to this unit, always power off before separating or putting together. To avoid damage to the unit, do not short the ANALOG OUT terminal and do not input voltage to the ANALOG OUT terminal.
Page 44
__________________________________________________ When taking measurements from ordinary NOTE lighting fixtures, the display will sometimes "roll", and be hard to read. This is generally due to fluctuations in the line voltage to the fixture or shadows caused by people in the area etc. Please note this in measuring. This instrument is equipped with a backlight in the display for measuring under the low illuminance.
__________________________________________________ Chapter 1 Overview 1.1 Product Overview The 3423 is suited for a wide range of applications involving illumination equipment, lighting work and facility management. The instrument has five measurement ranges, 20 lx to 200,000 lx, so it can measure the wide range of illuminance.

__________________________________________________ Chapter 2 Preparing for measurement 2.1 Installing or Replacing the Batteries WARNING To avoid electrocution, turn off the power switch and disconnect the AC adapter cord before removing the lithium battery. After replacing the batteries, replace the cover and screws before using the product. Do not mix old and new batteries, or different types of batteries.
__________________________________________________ 1. Remove the battery cover. 2. Installing or replace with all two new batteries. 3. Fit cover properly Collation number Measurement procedure Measurement range, Notes on batteries Production year Serial number 2.2 Using An Adapter WARNING Use an AC adapter that conforms to IEC 950 standards in respect to safety is rated for 6 V - 300 mA (with 10% stability), has 5 mm-dia.
__________________________________________________ Chapter 3 Measurement Procedure 1. Attach the supplied light sensor cap to the detector and set the POWER switch to (ON). 2. Press the 0 ADJ key if any digits appear in the LCD display. Then "ADJ" is indicated and the zero adjustment for all ranges is performed at the same time.

__________________________________________________ 7. Press the HOLD key to hold the reading. Press it again to release holding. (The analog output is not held. The range switching and zero adjustment is impossible, when holding. ) 8. Press the LIGHT key for more than one second to turn on the backlight.
Page 53
__________________________________________________ When the light sensor cap is not attached NOTE (more than approx. 1 lx is indicated), "CAP" is indicated. Make sure that it is attached. If performing the zero adjustment soon after powering on, several digits may not disappear. In this case, perform the zero adjustment again.

__________________________________________________ 6.2 Relative Spectral Response Characteristics in the Visible Spectrum Human perception of brightness ranges from 360 nm to 830 nm in the wavelength and is the maximum at 555 nm. The International Commission on Illumination (CIE) has established comparative standards for luminosity, setting the maximum perception for 1 and indicating the amount of perception of each wavelength by the relative value, and...
__________________________________________________ 6.3 Angled Incident Light Characteristics It is known that the luminance is proportional to the cosine of the incident angle of light (the cosine law). In the 3423, the shape of the light sensor, hook etc. is so made that it can follow the cosine law closely.
__________________________________________________ Chapter 7 Maintenance and Service 7.1 Message Indicates the measured value exceeds the measurement range. Indicates the zero adjustment is being performed. CAP Indicates that the light sensor cap must be attached to the detector, during the zero adjustment. 7.2 Cleaning To clean the product, wipe it gently with a soft cloth moistened with water or mild detergent.
If a problem is found, contact your dealer or HIOKI representative. Pack the unit carefully so that it will not be damaged during transport, and write a detailed description of the problem. HIOKI cannot bear any responsibility for damage that occurs during shipment. _____________________________________________...
