Operation 4. 1. Fix measuring transducer Insert the sensor into the corresponding slot of the right side of the instrument Connect the two measuring traverses (red & black) respectively into the wiring holes on the rear side of the instrument. 4. 2. Connect the Power Supply Plug the power cord into the power supply socket on the rear side of the instrument and turn on the power switch. Warn up the instrument for 5min after the display is activated. 4. 3. Turn the horizontal tumbler on the measuring sensor counter-clockwise to a desired position (not exceeding 45°) and put the coil to be measured onto the test bar of the sensor. Then reset the horizontal tumbler on the sensor. 4. 4. Measurement4. 4. 1. Connect the two terminal wires of the coil to be measured respectively with the red and black measuring traverses and make sure the electrical connections are in good condition in order to minimize the effects of contact resistance.4. 2. Phase DisplayWhen the instrument is working in a continuous measuring mode after being switched on, the number of the coil turns will be displayed on the screen. The mark "-" which may or may not be shown in front of the value indicates the two different winding direction of the coil.4. 3. "Measuring speed" Key (there is no "fast" measuring state when GW-9108 measures the resistance)When the "FAST" lamp is on, the instrument is working in a fast measuring mode (at a measuring speed of approx. 0.35s/time). Press the "MEASURING SPEED" key once again, the "FAST" lamp is off, and the instrument is working in a slow measuring mode (at a measuring speed of approx. 0.84s/time)4. 4. "Sound select" Key (GW-9108 does not have such function)Three pilot lamps ("PHASE", "OPEN CIRCUIT" and "MUTE") on the top right of the instrument are used to indicate three sound modes The instrument can be switched among these three sound modes by pressing the "SOUND SELECTION" key. If the "PHASE" lamp is on, the alarm will sound only when the phase mark "-" is displayed on the screen or there is an electric contact error. If the "OPEN CIRCUIT" lamp is on, the alarm will sound only when the coil to be measured has an open circuit or is disconnected or there is an electric contact error. If the "MUTE" lamp is on, the alarm will sound only when there is an electric contact error 4. 5. If the measured coil has an open circuit, or is disconnected or the coil resistance is greater than 50KΩ, the instrument will display "Error". 4. 6. When there is an electric contact between the coil and the test bar of the sensor, the "ELECTRIC CONTACT" pilot lamp on the instrument will illuminate. 4. 7. If the instrument is exposed to serious electromagnetic interference and can not work normally, make sure to eliminate the interference source before performing any measurement.V. Precautions 5. 1. Avoid any large electromagnetic interference around the instrument to avoid affecting the accuracy of the instrument. 5. 2. An open circuit inside the coil to be measured may affect the measurement accuracy. 5. 3. While putting the measured coil onto the test bar, make sure the lower end of the windings is set against the test table and the test bar is in the middle of the coil, in order not to affect the accuracy of the instrument 5. 4. Make sure there is a good contact between the coil lead wires and the wire clips. 5. 5. Prevent the test sensor from any collision and rotate it within approx. 45°avoid any damage. 5. 6. The test sensing assembly has been calibrated by using a special instrument and shall not be dismounted or modified without authorization, otherwise it will affect the measurement accuracy.VI.
