When in the main display, press the
left/right Arrow buttons until the HIGH
setting value display appears.

Detect the good workpiece and press the
[SET] button to capture the detected value.
"SEt" and the detected value blink alternately, and the value of the

good workpiece is fixed.

Detect the HIGH defective workpiece and press the [SET]
button to capture the detected value.
The median value of this detected value and the one captured in step 2 blinks.

HIGH setting value is fixed.

Press the right Arrow button until the
LOW setting value display of the main
display appears.

Detect the good workpiece again and
press the [SET] button to capture the
detected value.

Detect the LOW defective workpiece and press the [SET]
button to capture the detected value.
The median value of this detected

value and the one captured in

step 5 blinks.

LOW setting value is fixed.

Two-point tuning is completed.
Press the left/right Arrow buttons

to return to the P.V. value display.

■

Preset

This function displays the value obtained by adding or subtracting a

preset value to or from the detected value.

By using this function and the zero point correction function together,

you can set an arbitrary value as a reference point of the work.

Refer to "Preset Function" in the "GT2-100 Series User's Manual"

for details about the preset function.

■

Bank switching

By using the bank function, the setting values of the HH side, HIGH

side, LOW side, LL side, preset point, and the preset value can be

registered up to four patterns.

The bank switching is useful when there are multiple detection targets

since the pre-registered settings (four patterns) can be easily switched.

Refer to "Bank Function" in the "GT2-100 Series User's Manual" for

details about the bank function.

■

Limit output function

This function can detect and output the mechanical movement of

the spindle on the contraction and extension sides. The stroke end

of both sides can be detected, so this function can be used for

interlocking the device.

■

5-output

This function can increase the output levels to 5 levels: HH, HIGH,

GO, LOW, and LL. HH/LL can be set in the same way as HIGH/LOW.

Refer to "Setting 5-output" in the "GT2-100 Series User's Manual" for

details about the 5-output function.

■

Calculation function

The GT2-100N/100P can calculate various values using the detected

values of multiple detection points such as the maximum value or the

minimum value when an expansion head(s) is added (up to 10 units).

Refer to pages 2 to 3 of this manual for details about how to add an

expansion head.

The outline of the calculation function is shown below.

● Calculation mode

When "Calculation mode" is selected in "A1. Calculation mode", the

main unit outputs the calculation result, while the expansion unit

does not. Only the head indicator operates in the same way as the

one on the main unit. (Except when "C5. Reference difference" is

selected for the calculation method)

Refer to "Calculation with expansion unit" in the "GT2-100 Series

User's Manual" for details about the calculation function.

● Calculation only mode

When calculation only mode is selected in [A1. Calculation mode],

only the main unit outputs the calculation result, and the expansion

unit outputs the judgment according to each setting.

Refer to "Calculation with expansion unit" in the "GT2-100 Series

User's Manual" for details about calculation only mode.

■

Keylock

The keylock allows you to avoid erroneous button operation during detection.

When the keylock is active, setup operations other than changing

the display are disabled.

● Set the keylock

When keylock is active, setup operations other than main display switching,
[head selection] button and the [PRESET] button operation are disabled.
When in the main display, while pressing the [MODE] button,
press the "upper" Arrow button for at least two seconds.
The keylock display will appear for several
seconds and then change to the main display.

(Press for at least two seconds)

● Set full keylock

When full keylock is active, setup operations other
than main display switching and [head selection] button are disabled.
Press the "down" Arrow button for at least two seconds
while pressing the [MODE] button in the main display.

(Press for at least two seconds)

● Cancel the keylock or full keylock

Press "up" or "down" Arrow button for at least two
seconds while pressing the [MODE] button in the
main display when the keylock is active.
The keylock cancel display will appear for several
seconds and then change to the main display.

(Press for at least two seconds)

■

Initialize (Reset to the default state)

This function cancels all the functions you set and allows the

equipment to be reset to the default state.

When in the main display, while pressing the
[MODE] button, press the [SET] button five times.
"rSt.no" will appear.

Press the top/bottom Arrow buttons to select
"rSt.YES".

Press the [MODE] button.
"rSt.End" will appear.
Initialization is completed.

● Default value list

The setting items and the initial values to be initialized by are as follows.

Reference

• The calculation only mode is available only when

two or more expansion heads are connected.

• When the calculation only mode is selected, "C5.

Reference difference" cannot be selected for the
calculation method.

• When the calculation only mode is selected,

no sensor head can be connected to the
main unit (ID:00). Connect the included
"head dummy connecter" to the head
connector of the main unit.

Reference

The keylock can be set on the main display only.

Reference

• The initialization can be set on the main display only.
• The initialization cannot cancel "span adjustment results".
• Refer to "Calibration" in the "GT2-100 Series User's

Manual" for details about how to set "Span
adjustment" to the factory default state.

• During initialization, performing other steps than the

following ones stops initialization, and the display
returns to the main display.

Reference

When pressing and holding the top/bottom Arrow buttons
for more than 2 seconds in step 2, "All.no" appears.
When pressing either of the top/bottom Arrow button
to select "All.yES" and pressing the [MODE] button at
this point, all ID settings are initialized.
