1 .0 . I nt roduc t ion & Quic k St a rt I nst ruc t ions The DCF-900 and DCN-900 Coating Thickness Gauges represent the latest technology for the non-destructive measurement of coatings and plating. While both gauges are very easy and convenient to use, the first-time user should read this entire manual before operating the gauge for the first time to minimize operating problems and to fully utilize the instrument’s capabilities.

DCF: One (1) bare steel test plate for setting ZERO. DCN: One (1) bare aluminum test plate for setting ZERO. DO NOT USE ANY LUBRICANTS, SOLVENTS OR ABRASIVES. b.

8 .0 Cha nging t he Ba t t e ry The battery should not be removed while the power is on. Wait for the gauge to automatically power off (after 90 seconds of non-use) before replacing the battery. When to Replace: The gauge will automatically turn off if the battery drops below 7.4 volts DC. If the gauge turns itself off sooner than expected, or if it will not turn on, change the battery. Battery Type: Any high-quality 9-volt alkaline battery.

5 .0 Ope ra t ing Proc e dure 7 .0 5.1 Handle Probe Carefully. All probes contain sensitive circuitry. Handle them with care. Do not drop or swing them. AVOID DRAGGING PROBE TIP ACROSS A SURFACE. For best results, hold probe in place until reading is stabilized, then lift probe away from surface before re-applying to surface for subsequent readings. Clean pole tips with a dry cloth. DO NOT USE ANY SOLVENTS. 5.2. Taking Measurements 1. Press ON key to turn on the power. The LCD will display ru.n or run.

Setting “Calibration” Point 5. Place the plastic calibration shim on top of the bare metal part and then place the probe on top of the shim and bare part combination and measure as before. Note: the reading and determine if it matches the indicated value of the shim. If not, press and hold the or keys to increase or decrease the displayed value until it matches the shim value. Remove the probe from the test plate. The display will show CA.L or CAL. 5.3. Notes on Measurements 1.

6 .0 6.3 Changing Calibration Ca libra t ion 1. Turn the power on by pressing the 6.1 Introduction The DCF-900 normally does not require calibration before use. However, whenever the productor part material to be checked varies greatly from the steel test plate supplied, in either thickness or shape, it is best to check or verify calibration by using an uncoated sample of the actual product or part with one of the calibration shims supplied. Check calibration as noted in 6.
