Digital gauss meter HGS-20C - HGS-20C

Digital gauss meter HGS-20C

The Tasla meter is a special instrument used for inspecting & checking flux density ,which is also one of the most universally devices in the field of magnetic measurement.

Model HGS-20C digital Tasla meter is controlled by the SCM, which is suitable for handle operation.It can be used to measure DC or AC magnetic field and flux dencity.The device can be carried on one’s person. It is characterized by its wide measuring range,simple operation and clear display. It is still added with the function of maintenance such as holding Measure Value/Peak Value, As mT or Gs unit of display can be change over, Measuring range of 200mT or 2000mT can be chose, and others that as resetting zero by key and so on.

Reality Working Domain:

1) Magnetic field distribution of material surface

2) Working in the magnetic field produced from some instruments such as iron-removing device,magnet-selecting machine, magnet chuck, magnet spool and demagnetizing coil

3) Leakage Magnetic iron-surface

The connecting cable of the probe shall not be kneaded or pulled forcibly, the probe bracket shall not be beaten or impacted and the probe lead wire and welding spot shall not be contacted with other conductor or in short circuit.

a) Illustration of measuring field (see top fig.)

As holding the sensor,(no staff guage side)touch the surface of measuring object lightly.

b) The wrong method of holding the sensor:

No making the top of sensor to touch the surface of measuring object forcibly.(As the right Fig) So that it’ll damage the sensor easily.

Screen of Display

Manipulation Procedure

1. Connect Power
2. Insert the Hall probe into the socket on the panel (according to the arrow marking the sensor).
3. Press the key of the Power On/OFF in the panel and the digital display screen should display zero.
4. Select a suitable measurement range

Press the key RANGE switchover again and again , the measurement range would be transformed within 0-200 mT or 0-2000 mT.

1. Select DC/AC mode

Press the key DC/AC switchover again and again , the DC/AC mode would be selected.

1. Select display unit

Press the key(5) of conversion , the display unit would be transformed from mT to Gs.

1. Reset zero

Keep the sensor far away from magnetic field what it is not in the state of holding .If the display screen should not show “000”.you must press the key(7) to adjust it to zero.

Note: After change over the measurement range or transform the AC/DC mode , you all need to reset zero.

1. Measurement of Peak-value holding

Press the key(6) to change over normal measurement or Peak-value holding .

1. Loosen the cap of the Hall probe (see upper Fig).Place the effective position of Hall probe to touch on the surface of the resting material tightly (DC magnetic field) or at zone of measured magnetic field. The screen(8) will show the value of the magnetic field.

10. Reset Peak-value holding

When keeping the Peak-value holding , you need to measure new peak value and the forecast value will be lower forecast. Thus you could press the Reset button(7) to make it show a new peak value.

11. If the measurement is finished, the cap should be screwed up. It may be better to remove the battery from the case to prolong its time of use.

12. The Hall probe can be replacable .The difference from original probe to others is 2%.

Note: 0.1mT=1Gs 1T=10000Gs

Maintenance and Notes

1. As the statu of measuring ,if the instrument could not be adjusted to the zero or no display value. You’ll first check the power supply whether it is in the course of nature. Than check the probe whether it is normal or damaged. If the connecting wires are ruptured you could connected it according to the right Fig. Such terminal 1,2 are current, No. 4 and No.5 are terminals of voltage.

If you don’t find an damage in it , please send it to our company . It’s maybe wrong within the circuits.

1. The probe can’t burden force ,be cracked and squeezed.
2. While making the zero adjustment, the probe should be placed far away from the magnetic field for fear of the measurement error.
3. The instrument is guaranteed to keep in good repair for 18 months except the probe.
4. Do not use the instrument in unappropriate conditions.
5. If you find the value of testing shows errors in the states of measurement, you could loosen the handle of the probe to adjust the screw of the resistance tinily.

If don’t ensure that the instrument is operated correctly as described below, there would be error or

mistake.

1,Don’t attempt to repair, or disassemble, and any reconstruct this instrument.

2, Use only recommended power accessories.

3, Don’t connect the terminals of the outer power supply reversely. the inner is plus, the outer is minus.

4, Don’t drop this instrument or the probe down ground. It’ll be damaged by strong vibration.

5, Do not allow hands or other objects with dirt to touch the probe.

6, Avoid using, placing or storing the instrument in places subject to strong sunlight or high temperature, as well as humidity, water, oil, rust air, vibration and others.

7, It would be used and stored up in temperature range

8, You should not move the instrument rapidly between high and low temperature to avoid condensation.

9, Never place the instrument in the places close to the machine generating strong magnetic field, such as magnet-charger, demagnetize coil, microwave oven, electric welding equipment electric motor and etc.

10,In conclusion, we suggest you calibrate the instrument in time.
