the origin re-detection function will be canceled (except during error
detection).
4 Basic Operations
4.1 Preset
The current value of the Counter can be set to an arbitrary value at any point
within the Linear Gage measuring range.
Tips
• Switch the current Peak mode setting to the normal measurement in advance.
For details, see "4.2 Peak Mode Setting" (page 5).
• The factory default setting of the Preset value is 0.
• To set the current value of the Counter to 0 after you have modied the Preset
value, set the Preset value to 0. The maximum value, minimum value, and TIR
value that have been set in Peak mode will be set to 0 at this time.
• For the EG-101D (gage type is set to "ABS") and EG-101Z (origin detection
function is enabled) Counters, the effective Preset count is one million times.
As an example, the procedure for presetting the datum to 10.005 mm is
explained.
1 Repeatedly press [BANK] to select BANK 0.
»The BANK indicator turns off.
Tips
While [BANK] is pressed down, the currently selected BANK number
is displayed. When the key is released, the Counter will return to the
Counter display.
2 Press [Fn] to switch to setup mode.
»The previous Preset value will be
displayed. (The example on the right
shows the previous value as 10.000.)
3 Press [MODE].
»The input digit will shift to the right. (The
currently selected digit will blink.)
4 Press [P.SET].
»The Preset value will be modied.
Tips
• The ± sign is also set at the most signicant digit. To set the Preset value to a
negative value, repeatedly press [P.SET] until the Sign indicator lights.
• To cancel the input, press [Fn]. The Counter will return to the Counter display.
5 Repeat step
3
and step
4
until the least signicant digit has
been set.
»The least signicant digit will blink.
6 Press [MODE].
»The Preset value will be applied (the
least signicant digit stops blinking).

7 Press [Fn].
»The Counter will return to the Counter display.
8 Press [P.SET].
»The current value will be changed to the Preset value that was set.
4.2 Peak Mode Setting
The maximum value, the minimum value, and TIR value are constantly
calculated in the Counter. By switching the mode, you can display the
counter value according to the intended application.
Mode Description
Normal
measurement
Counts the movement (displacement) of the contact
point of the Linear Gage, and then displays the
value successively.
Max. hold
measurement
Displays the maximum value (MAX) measured
during the measurement. The display will not
change until a new maximum value is measured.
Min. hold
measurement
Displays the minimum value (MIN) measured during
the measurement. The display will not change until
a new minimum value is measured.
TIR measurement Displays TIR value during the measurement = TIR
(maximum value - minimum value). The display will
not change until either a new maximum value or
minimum value is measured.
Procedure for switching Peak mode
1 Repeatedly press [MODE] until the desired mode is displayed.
»The mode will switch as follows:
Normal

Procedure for clearing the peak value
1 Press [MODE].
»Peak mode will be set.
2 Press [P.SET].
»The peak value will be cleared (MAX = MIN = current value, TIR = 0).
4.3 Switching the Tolerance Bank
When setting 3-step or 5-step tolerance values, 3 sets of tolerance value
settings can be saved in internal counter memory called a BANK. You can
recall the saved tolerance value settings by switching the BANK.
Tips
• For details about tolerance value settings, see "4.4 Tolerance Value
Setting" (page 5).
• The BANK can also be switched by an external signal.
This section explains how to switch the BANK.

»The BANK number will be switched.
»The BANK indicator will switch according to the selected BANK number as
shown in the gure below.

Tips
• The BANK indicator will switch in order from BANK0 through BANK3 each time
you press [BANK].
• While [BANK] is pressed down, the currently selected BANK number is
displayed. When the key is released, the Counter will return to the Counter
display.
• The tolerance judgment function is disabled when BANK0 is selected.
4.4 Tolerance Value Setting
There are 2 settings for the tolerance value: 3-step and 5-step.
Tips
• Set the value of parameter number 21 to 0 (3-step tolerance) or 1 (5-step
tolerance) in advance.
• For details about I/O output, see "5 External Input/Output Function" (page 6).

5 External Input/Output Function
This product has an I/O connector that enables data communication with
external equipment. There are 2 types of external output modes: "Tolerance
judgment output mode", which outputs the tolerance judgment result, and "BCD
output mode", which outputs the counter data with BCD. Also, you can activate
the Preset function and activate HOLD on the counter value through external
signal input.

Tips
• After acquiring the counter data, there is a maximum 10 ms delay before the
tolerance judgment result is output.
• For EG-101D, the length of time until the tolerance judgment result is output
after the counter data enters in the Specication range depends on the
connected equipment, such as the Linear Gage.

6 Troubleshooting
6.1 Troubleshooting
When the Counter does not operate as expected, refer to the cause of the
trouble and the solutions shown below:
Cause Solution
Symptom 1: The counter value is incorrect (not counting).
Parameters are not correctly
set for the type of the Linear
Gage, etc.
Set correct parameters. For details,
see "3.2 Basic Parameters" (page
3).
Peak mode (MAX or MIN is lit)
is active.
Cancel Peak mode. For details, see
"4.2 Peak Mode Setting" (page 5).
The HOLD signal (UNIT is
blinking) is being input.
Check the external input.
Calculation with a constant
function is set.
Cancel calculation with a constant
function. (Set parameter number 16 to
0.)
Symptom 2: Cannot execute Zero setting.
Peak mode is active.
Cancel Peak mode. For details, see
"4.2 Peak Mode Setting" (page 5).
The Preset value is a value
other than 0.
Set the Preset value to 0. For details,
see "4.1 Preset" (page 4).

Cause Solution
Symptom 3: The Counter executes Zero setting unexpectedly.
A power interruption (sudden
drop in power voltage) has
occurred.
Check the power supply. For details
about how to cancel the error, see
[------] in the List of Error Codes.
"6.2 List of Error Codes" (page 8)
Symptom 4: BCD output is not working.
BCD output is not enabled. Enable BCD output. (Set the value of
parameter number 20 to 1.)
Output logic is not correct. Select the output logic that is
appropriate for your application by
setting parameter number 24.
Command mode is active. Enable interval mode. (Set the value
of parameter number 22 to 1.)
Symptom 5: Cannot modify the parameter settings.
"Set parameters" (set value 1)
has not been set for Parameter
mode.
Set the value for parameter number
00 to 1. For details, see "3.1
Procedure for Setting Parameters"
(page 3).

Tips
• If the NOM signal is "H": When an error occurs in 3-step or 5-step tolerance
judgment output (the value for parameter number 20 is 0), both pin numbers 3
(L1) and 7 (L5) will be "L".
• If an error occurs while you are setting parameters, the Preset value, or the
tolerance value, the error will be displayed after you return to the counter state.
However, the error signal will be output immediately to any external output.
• Errors can also be canceled with an external PSET signal.
• For EG-101D, all decimal points blink for about 8 seconds when an error is
canceled.
