4 For moreinformation visit our website at ABOUT YOUR GAUGEThe Elcometer 204 Steel Ultrasonic Thickness Gauge is a handheld Gauge for fast and accuratemeasurement of the Thickness of Gauge is capable of measuring the Thickness of material such as steel plate with accuracy as high as mm ( "). The principal advantage of Ultrasonic measurement over traditional methods is thatultrasonic measurements can be performed with access to only one side of the material being WHAT THIS BOX CONTAINS Elcometer 204 Steel Ultrasonic Thickness Gauge Transducer Bottle of couplant, 120ml (4 fl oz) Battery, 2 x Carrying case Operating instructionsR3enYour Gauge is packed in a cardboard and foam package.

5 Please ensure that this packaging is disposed ofin an environmentally sensitive manner. Please consult your Local Environmental Authority for maximise the benefits of your new Elcometer Ultrasonic Thickness Gauge , please take sometime to read these Operating Instructions. Do not hesitate to contact Elcometer or your Elcometersupplier if you have any STANDARDSThe Elcometer 204 Steel Ultrasonic Thickness Gauge can be used in accordance with the followingNational and International Standards ASTM E 797, EN GETTING FITTING BATTERIESYour Gauge may be used with dry cell batteries or rechargeable x LR6 (AA) alkaline batteries are supplied in the fit or replace batteries:1.

6 Locate battery compartment cover at top of Unscrew battery compartment Referring to battery polarity instructions on rear of Gauge , insertbatteries into Gauge ensuring correct Replace battery compartment the batteries from the Gauge if it is to remain unused for a longperiod of time. This will prevent damage to the Gauge in the event ofmalfunction of the the battery voltage is low the entire display will start to flash. Whenthis occurs the batteries should be : Alkaline batteries must be disposed of carefully to avoidenvironmental contamination. Please consult your local environmentalauthority for information on disposal in your not dispose of any batteries in : An interface is located on the bottom of your Gauge .

7 This interface is used to program the Gauge atthe factory and has no function for users of the 204 Steel UltrasonicThickness GaugeRPRB0 INMMONOFFB attery compartment THE TRANSDUCERThe transducer transmits and receives the Ultrasonic energy orsound waves that the Gauge uses to determine the Thickness ofthe material being transducer connects to the Gauge via the attached cable,and two coaxial connectors. The orientation of the dual coaxialconnectors is not critical; either plug may be fitted to transducer must be used correctly in order for the Gauge toproduce accurate, reliable diagram shows the two semicircles of the wearface and thebarrier separating them.

8 One of the semicircles transmitsultrasonic sound into the material being measured, and the othersemicircle receives the sound echoes back into the the transducer is placed against the material beingmeasured, it is the area directly beneath the centre of thewearface that is being THE KEYPADKeyFunctionsPress to switch the Gauge on or switching off, the Gauge retains all of its the Gauge is idle for 5 minutes, it will switch itself to change units (metric/imperial)Switches the display backlight between three settings; on, off and auto. ON - backlight is on OFF - backlight is off AUTO - backlight automatically illuminates while the Gauge is making a measurement and switchesoff after several seconds (to conserve battery life).

9 Press to zero the Gauge - see Probe Zero on page THE DISPLAYINMM/ s Stability indicator One bar - no readings are being taken Less than 5 bars - reading is unstable and may be inaccurate More than 5 bars - reading is stable(Refer to Read display onpage 9 and Transducers onpage 16 for information onhow to achieve a stablemeasurement).Units (IN, MM, IN/ s, MM/s) Thickness value/TextR8en3 TAKING A READINGD isclaimer: Inherent in Ultrasonic Thickness measurement is the possibility that the instrument will use thesecond echo rather than the first echo from the back surface of the material being measured. This mayresult in a Thickness reading which is TWICE what it should responsibility for proper use of the instrument and recognition of these types of phenomenon restssolely with the user of the BEFORE YOU START Prepare the.

10 See Condition and preparation of surfaces on page 17. Zero the .. See Probe Zero on page PROCEDURE1. Apply couplantFor the Gauge to work correctly there must be no air gaps between the transducer and the surface ofthe material to be measured. This is achieved using a material called a the transducer is placed on the surface, put a small amount of the couplant supplied with thegauge on the surface of the material. Typically a single drop is Place transducer onto surface of material to be measuredPress the transducer into the couplant. Moderate pressure on the top of the transducer using thethumb or index finger is sufficient.
