Connecting and Mounting the Sensor Head
Mounting the Sensor Head
Attach the sensor head using the dedicated mounting bracket.
When you attach the sensor head, be careful not to touch the aperture. Doing so
may lead to malfunctions.
Install the sensor unit (including its metal parts) so that nothing
touches it during measurement. Failing to do so not only prevents
proper measurements of static electricity but may also lead to
electric shock and product breakdown.
Do not cover the area around the temperature/humidity sensing
unit. Doing so will prevent you from correctly measuring the
ambient temperature/humidity.
Measurement area
The following figures briefly show the measurement area of the SK-050.
The measured value is the average of the values detected within the measurement
area as seen in the figures.
*1 The SK-1050 (expansion unit) does not have brown, blue, or light blue wires.
Power is supplied to the expansion unit through the SK-1000 (main unit).
Use D-class grounding to ground the blue wire.
*2 The analog output (surface potential) specifications change according to the
measurement range.
The analog output can be set to one of the following values when the power is
first turned on and when initializations are performed.
None (OFF), -5 to 5 V, 0 to 5 V, 1 to 5 V, or 4 to 20 mA
" Operation When the Power is Turned on for the First Time" (page 7)
" Initial Reset (Initialize)" (page 8)
*3 In addition to the above values, you can select from the following options for
external input.
Bank B input or do not use (OFF)
" 10. External input" (page 15)
*4 When you expand the system to 6 or more units, use a power supply voltage
of 20 to 30 V.
• This device's 0 V power supply wire, analog output GND wire,
and grounding wire are all shared. Ensure that an electric
potential difference does not occur between their terminals due
to wiring or due to electric potential differences between
NOTICE
external devices. Failing to do so may lead to accidents or
breakdowns involving the external devices and this product.
• Use power supplies that are isolated from each other or so that
negative grounding is present between them. You cannot use
positive grounding.
Measurement distance
The SK-050 provides a high-precision mode and a wide-range mode. Each mode
offers different measurement distances between the sensor head and the target.
The figure below shows the reference distance for measurements in each
measurement mode. The reference plane is the bottom surface of the sensor head.
Attaching the ion balance monitor unit (OP-87934)
Fix with screws using the mounting holes in the sensor's main body and those of
the ion balance plate.

R.V. (Internal Measurement Value) and P.V. (Judgment Value)
This section describes R.V. (Internal Measurement Value) displayed on the sub
display (lower level) and P.V. (Judgment Value) displayed on the main display
(upper level).
R.V. (Internal Measurement Value)
R.V. (Internal Measurement Value) is the value displayed when a target is inserted
into the measurement range. Only the charge potential can be displayed.
* R.V. = Raw Value
P.V. (Judgment Value)
P.V. (Judgment Value) is the value to set the judgment output to ON/OFF
according to the tolerance setting value. Also, the analog output is output based
on the P.V.. Only the charge potential can be displayed.
* P.V. = Present Value
"Changing the Tolerance Values" (page 9)
The Judgment value (P.V.) and the Internal Measurement Value (R.V.) are typically
the same value. However, when the hold function, step-count filter, or the calculation
function is used, they will become different values.
"6. Hold Function" (page 12)
