4. Hold the fieldmeter 1” away from the charged
surface. Two beams of light will form concentric
circles when the meter is the correct distance, 1”
away, from the surface. The measurement
accuracy is dependent on a stable ground reference and the 1 inch measuring distance. It is also
dependent on the “aspect ratio”, relating the size of the object to be measured to the measurement
distance. This aspect ratio should be at least 3 for
best accuracy, i.e. the object should be at least a
3 inch square when measuring at a 1 inch distance. Accurate measurements may be made at other
measurement distances by scaling the meter range and obrving the proper aspect ratio. For exam
ple, at a measurement distance of 3 inches, multiply the meter reading by 3 to give a range of 0 to 60 kilovolts. For accuracy, the object being measured at this
distance should be at least a 9 inch square.
5. A bar graph and a digital display on the 19430
汤圆由来displays the voltage of the charge. Press HOLD if you want to hold the display of the measured charge.
6. To turn off meter: Press POWER if you have not
ud the HOLD mode.
If you have presd HOLD and
wish to retain the
meter reading for the next u,
press the POWER button to
turn off the 19430.
If you have presd HOLD and
do not wish to retain the meter
reading for next u, press
HOLD then POWER.
If the 19430 is left on for five minutes, the unit will beep five times then turn itlf off automatically. To disable this feature, simply press and hold the red power button for at least three conds when turning the 19430 on. Three beeps and the A-OFF display indicates that the feature has been disabl
ed.
Results
A display of [+] or [-] next to the digital numeric value reprents the polarity of the static charge being measured. In addition, the color of the bars in the bar graph indicates the polarity of the static charge. Red and blue bars indicate positive and negative charges respectively.
During a static charge measurement, if the digital display starts flashing along with a continuous beep, stop taking the measurement. The static charge is greater than the meter can measure. Attempts to measure too high a charge may damage the nsor.Operation For Ion Balance (Offt Voltage) Measurement
NOTE: The Digital Static Locator Ion Balance measurement feature should not be ud to measure the ion balance of static bars. It may be ud to mea-sure other ionizers for ion balance (offt voltage).
1. Depress the plate asmbly relea button on either side of the fieldmeter to remove the charge plate
asmbly.
2. Inrt the plate asmbly into the other end of the
fieldmeter (the end with the “Static Locator”) until it
clicks into place.
NOTE: Ion Balance plate asmbly must not move during measurement.
3. The conductive ca must be grounded using the
supplied ground cord. It is imperative for accurate ion balance and to drain any charge that has
developed prior to measurement.
4. To turn on the ion balance measuring circuit, press the blue IB button.
5. Turn nsor toward an uncharged area.
6. The meter reading should be zero (0). Press the
Zero button if it is not.
7. Hold the fieldmeter centered in front of the ionizer at any convenient, repeatable distance, such as 1 foot.
8. A bar graph and a digital display on the 19430
displays the ion balance information. Press HOLD if you want to hold the display of the measured
charge.
9. To turn off the meter:
Press POWER if you have not ud the HOLD
mode.
If you have presd HOLD and wish to retain the
meter reading for the next u, press the POWER button to turn off the 19430.
If you have presd HOLD and do not wish to
retain the meter reading for next u, press HOLD then POWER.
10. Depress the charge plate asmbly relea buttons on either side of the fieldmeter to remove the charge plate asmbly. Store the plate on the opposite end, pressing it until it clicks into place.
