1 __________________________________________________ Introduction Thank you for purchasing this HIOKI "3423 LUX HiTESTER". To get the maximum performance from the tester, please read this manual first, and keep this at hand. Inspection When the unit is delivered, check and make sure that it has not been damaged in transit. In particular, check the accessories, panel switches, and connectors.
2 __________________________________________________ Safety Notes WARNING This product is designed to conform to 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 product. 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 product defects.
3 __________________________________________________ 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. Indicates DC (Direct Current). Indicates the ON side of the power switch.
4 __________________________________________________ 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).
5 __________________________________________________ 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. This product is not designed to be entirely water- or dust-proof. To avoid damage, do not use it in a wet or dusty environment.
6 __________________________________________________ NOTE When taking measurements from ordinary 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. The brightness is set lowest, for the low consumption of the batteries.
7 __________________________________________________ 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. It can measure, with the detector separated from the display and has a large LCD easy to read in the display, for user's convenience.

11 __________________________________________________ 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. Also, be careful to observe battery polarity during installation.
12 __________________________________________________ 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. terminals and has a center pin with negative polarity.
13 __________________________________________________ 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. 3. When "ADJ" disappears, remove the light sensor cap and put the detector where the measurement is taken. 4.
14 __________________________________________________ 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. The reading is held automatically, when it lights. The backlight lights for approx. eight seconds, and then goes out automatically. (Holding is not released after the backlight goes out.
15 __________________________________________________ NOTE When the light sensor cap is not attached (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. Do not connect or disconnect the AC adapter, and the detector and the display, with the POWER switch on.

26 __________________________________________________ 6.3 Angled Incident Light Characteristics Deviation from consine 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.
27 __________________________________________________ Chapter 7 Maintenance and Service 7.1 Message OF Indicates the measured value exceeds the measurement range. ADJ 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.
28 __________________________________________________ 7.3 Calibration and Repair The calibration interval for the 3423 is two years. It is recommended to calibrate it every two years, for accurate measurement. Contact your nearest service representative. If the unit is not functioning properly, check the batteries.
