1.0 INTRODUCTION 7.0 The DHT-2 Textile Moisture Meter accurately measures the percentage (%) of humidity contained in textiles. It can be equipped with different transducers (called “electrodes”), according to the type of material being tested. 1.1 Principle of Operation When the DHT-2 probe is placed in contact with a textile sample, it measures the electrical conductivity of the material, which varies based upon the type of material under test, and the amount of moisture present.

.0 MEASURING PROCEDURE 3.1 Preparation 1. Connect the gauge to the electrodes holder using the supplied Connection Cable. 2. Unscrew the upper plastic ring of the electrode holder, insert the desired electrode, replace the plastic ring. 3.2 Taking A Measurement 1. Press the Power On/Off key. 2. Select one of the built-in measurement scales by pressing the < key until the desired material name appears on the display (see photo). For other materials, select the 0-100 scale. 3.

.0 CALIBRATION Need information on why and when to perform a calibration. To calibrate the DHT-2, please perform the following procedure: 1. Turn the instrument On. 2. Remove the four fixing screws on the rear of the instrument. Carfully remove the rear of the plastic case and set it aside. 3. Locate the 1 K Ohm and 1 M Ohm trimmers. See photo A. 4. Connect the reference probe of beginning of the scale (29%) Not sure what this means. A 5.
