first measurement.
3. Check the three segment battery indicator in the top, right screen. If the meter’s power is
low, replace the battery. Low power may effect the measurement function.
4. Measuring static:
a. The meter should be 25 mm (.98inch) away from and parallel to the surface to be
measured.
b. The WD button turns on the LED guide.
c. Press the HOLD button to keep the measured data on the display after a test is
taken. Press the HOLD button again to resume detection mode.
Notes:

2. Do not zero out the meter in presence of static. This may effect the accuracy.
3. Make sure the static sensor if clean. Do not insert anything into the sensor. This can cause
damage.
4. Do not measure static charges over 2000volts. This can damage the meter. Note: It typically
takes a charge of greater than 2,000 volts for a person to feel the “zap”. If you can sense the
charge, do not measure it.
5. The meter is sensitive to drops and collisions. This can cause malfunctions.
6. Do not disassemble the meter. If there is an problem, contact Transforming Technologies.
