Page 5: Intended Use And Measuring Principle
3. Intended use and measuring principle The Coulombmeter Type HMG 11/03 is used for contactless measurement of the charge transferred in a spark. It is not suitable for measuring surface charges, which only give a measured value on contact. For a proper measurement, a spark must occur when the measuring ball approaches the test specimen. -
Page 6: Coulombmeter Circuit Principle
3.2. Coulombmeter circuit principle The charge transferred from the charged test piece via spark/brush discharge to the ball electrode is stored in capacitor C and then discharged to ground. The current, flowing across the measuring resistor, is measured. By an integral calculation, the charge is calculated from current over time. Q = I The microcontroller "MP"... -

4.11. Function of the buttons (switches) R-switch (r) ↑ upward ↓ downward Only active in measurement operation! The measurements are reset and the second counter restarted in both switch directions. Upward: saves the measured value Downward: deletes the measured value. Exception: When the timer function is active, the timer can be restarted by pushing up until a valid measured value is recorded without previously having to save something. -

Page 19: Exceeding The Measurement Range
6.2. Exceeding the measurement range If the following appears in the display, then the measurement range for negative charges is exceeded (blue minus sign as prefix) the measurement range for positive charges is exceeded (brown plus sign as prefix) Measured value or measurement range exceeded. The actual value exceeds the displayed value, thus the measurement must be discarded. -
Page 20: Achieving Optimum Measurement Results
6.3. Achieving optimum measurement results Electrostatic charges are generally subject to climatic influences. Therefore, measurements on charge transfer should no longer be carried out at a rel. humidity > 50 %. Because the measured values are also influenced (albeit to a lesser extent) by the abs. humidity, a higher rel. humidity can be tolerated at 10 °C, for example, than at 30 °C, for example. -
