Product calibration

1, Calibration environmental conditions

The calibration environmental conditions and their requirements are as follows:

a) Ambient temperature: 20 °C ± 5 °C

b) Relative humidity: 30-60%

c) There are no measurable electric, magnetic, positive and negative ions around

d) Ground wire, ground wire resistance <100Ω

2, Calibration equipment

The equipment used for calibration shall be calibrated by the metrology technical organization to meet the calibration requirements and within the validity period.

Calibration equipment mainly includes: DC high voltage meter, DC high voltage power supply, standard flat electrode, distance adjuster and so on. The test chart is located on the center line of the calibration plate. The block diagram of the non-contact electrostatic voltmeter calibration device is as follows:

The equipment and equipment requirements are as follows:

C——calibrated product: static test table

D1——DC high voltage power supply: output range -30KV～+30KV, continuously adjustable, or minimum step 1V, the measurement uncertainty is less than 1/4 of the allowable error limit of the calibration table;

D2——DC high voltage meter: measuring range -40KV～+40KV, the measurement uncertainty is less than 1/4 of the allowable error limit of the calibration table;

D3——Standard plate electrode: The plate electrode should be round or square rounded. The radius of curvature of the edge of the electrode should not cause corona. It is recommended to wrap the edge of the electrode with insulating material; the area of the plate should be large enough. The diameter or side length should be no less than 0.4m. Our calibration plate size is 600mm*600mm square stainless steel plate.

——Protection resistance: The resistance of the resistor should be >20KV, the protection current and the current of the human body are <5mA, and the resistance value meets the requirements of the following formula:

Where: for protection of resistance, the unit is ohm (Ω);

The resistance of the insulating bracket is in ohms (Ω), the resistance is >1013Ω, and the compressive strength is >25KV.

The above two resistors, their different resistance values, may cause the detected static voltage values to be different under the same standard voltage.

S1 - insulated bracket

S2——scale, measuring range: 5mm～700mm, measurement uncertainty less than 0.5mm

S3——Distance adjuster: Place the test meter on the calibration device. The front end of the test chart should be extended. The geometry and material of the support should be minimized to affect the electric field distribution around the front end of the test chart.

1, Instructions for use:

(1) Install the battery and switch machine:

First open the battery compartment cover on the back of the static voltage detection meter, and put in the 2 7# power supply battery as standard in the package to open the switch. See the picture above for details.

(2) Preparation before testing:

In order to ensure the normal use of the static voltage detection table, first confirm that the three-segment power display on the display screen is marked as full (or enough power), and then the parameters of the visual screen are clearly visible. Check whether the various function keys are clear. Can be used normally. See the display function diagram for details:

(3) Detecting static electricity on the surface of the object:

When using, the static detection window of the test table should be parallel to the surface of the object to be measured, and 25mm away from the surface of the object to be measured, which is the standard detection distance; if conditions permit, it is recommended to use a ruler for distance calibration.

After measuring the data, you can press the data hold button to keep the measured data on the display; press the data hold button repeatedly to resume the detection status.

2, The button description

Power: Short press to turn on (the screen displays ON), long press to turn off (the screen displays OFF)

Zero: long press to clear

BL: short press, turn the backlight on or off

WD: Short press, turn LED on or off focus

HOLD: Short press, the data remains unchanged; press again again to resume real-time display

3, Matters needing attention

1) In order to use the device correctly, please read the instruction manual carefully before use.

2) Please operate at the specified ambient temperature (-18 to 50 °C).

3) Do not touch the static detection window with a sharp object.

4) The display screen should not be stressed by external force to avoid breakage.

5) The product is strictly prohibited from touching water stains, otherwise abnormalities may occur, resulting in electric shock or fire.

6) Do not touch the static electricity detecting head during testing.

7) Ensure that the sensing window is free from particles and dust.

8) There should be no obstruction between the test table and the object to be inspected, otherwise the accuracy of the test result will be affected.

9) There should be no electrical equipment that affects the test table within the test range. Otherwise, internal equipment and chip failure and damage may occur.

10) In order to accurately measure the charged object, the plane of the detection table detection window shall be parallel to the surface of the object to be measured.

11) Turn on the power button for 5 seconds. Otherwise, sometimes the data display will be unstable.

12) When the charged object is smaller than the calibration plate, the measured value is smaller than the actual electrostatic value of the charged object.

13) When the charged object is larger than the calibration plate, the measured value is larger than the actual electrostatic value of the charged object.

14) It is not allowed to zero in the state of static charge or in the static measurement process (non-electrostatic calibration process); if zero is adjusted during static test, the displayed electrostatic value will be zero.

15) Do not install in high-voltage equipment, such as high-voltage power supply, electrostatic generator, ion generator, and consumer, high voltage will affect the performance and detection accuracy of the test.

16) If the detection range is exceeded, it may cause a product failure.

17) This detector is a precision device and should not be disassembled.

18) The product is subject to mechanical shocks such as drops and collisions, which may cause malfunction.

19) It is strictly forbidden to disassemble the product without authorization. Internal maintenance and repair must be carried out by professionals.

20) The product is designed to detect static electricity on the surface of the object. It is strictly forbidden to use for other purposes. Any abnormal use may cause machine malfunction, electric shock, fire and other hidden dangers.

4, Use fault analysis
