It can. Consult with Koganei.

Use a duct and filter, for exhaust air processing. In
addition, prepare a compressed air source, and a power
supply (100VAC), regardless of whether a dust collector
blower fan is used or not.
Koganei makes no particular designation. Select a duct
with a nominal diameter of
φ
75 [2.95 in.].
The ground can be created from either the main body or
the power cable.
Use “actual measurement data output mode” when you
want to know the instantaneous value of the charged
object. When the charge variation is so large that the
measured value is difficult to read, use the “averaged data
output mode” to average and display the measured
potential so that the measured value will be easier to read.
This sets the maximum and minimum voltages, and when
a charge exceeding the range defined by these two values
is detected, outputs an alarm.
“Input-output response time” refers to the time required in
“averaged data output mode” for outputting measurement
data equivalent to the actual charge amount. “Data output
cycle” refers to the timing for outputting the measured
data.
The LED lights up when the sensor is abnormal, and
blinks when the setting threshold voltage is exceeded.
There is no reset function for abnormal output in the EP
sensor. A sensor abnormality is treated as a malfunction,
and should be either repaired (consult with Koganei) or
replaced with a new sensor.
When the sensor (detector) stops transmitting, this is
output as a sensor abnormality. Since subjecting the EP
sensor to a strong shock can result in an abnormality, be
careful when operating.
Use the zero calibration function switch when setting the
reference value (zero adjustment) before charged object
measurement.
See the EP Sensor Catalog No.BK-R0002.

expressions: “rdg (reading)” and “FS (full scale).” “rdg”
expresses the error in relation to the read value, and “FS”
expresses the error over the entire measurement range. In
addition, “digit” is the minimum unit of display.
Since the sensor is affected by temperature, humidity,
electric field, ground status, and noise, use the sensor in
an environment that minimizes fluctuation.
Since the EP sensor is not a measuring instrument,
calibration cannot be performed. However, Koganei is
ready to perform inspections and adjustments at customer
request. Customers desiring this service are requested to
consult with Koganei.
Since the data output cycle can be as short as 100 ms,
measurements can be obtained so long as the workpiece
does not completely pass by within the cycle period.
No, it cannot be used.
The support software can display and save the various
settings and measurement data. It can be downloaded free
of charge from the Koganei website.
