1.1 EV Counter
1.1.1 Features
•Three models of EV counter (EV-16P, EV-16D, and EV-16Z) are
available according to the linear gage connected. The applicable
gages for each model are as follows.
EV-16P: LGF, LGB, and LGE series linear gage (excluding the mod-
els that output sine waves)
EV-16D: LGD and LGS series linear gage
EV-16Z: LGF-Z series linear gage
•EV counter is a multi-axis counter to which plural gages can be con-
nected. The maximum number of gages that each model can connect
is 6.
Only EV-16Z supports the origin embedded gages.
•The origin function of EV-16Z realizes high-speed response and re-
duces the time and labor taken by referencing with a master each time
the power is turned on.
•With the RS LINK function a maximum of ten EV Counter units can
be linked. This makes it possible to construct a system consisting of a
maximum of sixty linear gages through one RS-232C port, which is
on, for example, a personal computer.
•The display unit is of a separate type (optional) which takes in-line
use into consideration.
•Depending on the external devices to be connected and uses, the fol-
lowing I/F connection and output mode can be selected:
[Connection I/F]
Tolerance judgment output
Separately outputs the judgment result from each CEL.
Segment output
Outputs the range specified by the external signal after evenly di-
viding it into ±ten stages.
The objective CEL to be output and its range can be specified with
the external SET signal.
BCD output
Output of sign and 6-digit data.
The objective CEL to be output can be designated with the external
SET signal.
RS-232C/RS LINK
A maximum of 10units/60 channels can be linked.
Preset and tolerance values can be remotely controlled.
Can be used simultaneously with other I/O devices.
[Output mode]
NORMAL mode (factory-set default)
Calculation mode
Calculate the sum, mean, maximum, minimum, and width be-
tween the specified CELs and outputs the results.
High-speed mode
Quickly outputs the specified CEL.

This chapter outlines the features of the EV
Counter for linear gages.

Gage selector:
By setting the appropriate parameters it is possible to con-
nect a single gage output either to one internal counter or to
multiple internal counters. With this function, multiple ori-
gins and tolerance setups can be set for a single gage.
Internal counter:
Origin setup, peak measurement, and tolerance setup can be
performed individually for each of the six internal counters
(CEL1 - CEL6).

1 - 8 No. 99MBC034B
Calculation function:
Each of the internal counters has a specific calculation func-
tion. Therefore, calculation can be performed between the
counters specified by the parameters.
Output function:
Either RS-232C, BCD, tolerance judgment, or segment out-
put can be selected. The objective CEL to be output can be
selected using the RS-232C command or SET signal.

2.1 Installing the EV Counter
Both the front and rear panels of the EV Counter have four
mounting holes. Use the fixing legs and junction brackets which
come as the standard accessories to install the EV Counter.
a) The fixing legs
(1) Attach the fixing legs (4 places) on
the counter main unit using the
supplied screws.
(2) Use the oval hole provided on each
fixing leg to secure the counter to
an appropriate surface.
b) The junction brackets
Use the junction brackets and sup-
plied screws to join the two panels
along the vertical.
SETUP
This chapter describes the method used to in-
stall and connect the EV Counter and make its
initial conditions.

2 - 2 No. 99MBC034B
2.2 Connecting Cables
IMPORTANT •Connection should be made only after the
power to the main unit and to the partner device
of the connection have been turned off. Other-
wise, the counter main unit and the connected
device will be damaged.
•Use a 12 - 24VDC power supply with a control
output current of 1A or greater. Do not draw
power from a source which is used by high-
power equipment.
•Do not route the power cable, I/O cable, RS-
232C cable, RS LINK cable, or gage connec-
tion cable with other power cables.
•Use a shielded I/O cable not longer than 3m.
•Always ground.
•Each cable should be secured (to, for example,
the main body of the device).
2.2.1 Connecting gages
(1) Sequentially connect the required number of linear gages to
the corresponding connectors, starting with the INPUT A
connector.
(2) If the EV-16P or EV-16Z is connected to a gage that does
not have a resolution of 1µm, refer to section 3.1 Setting
Parameters (with D-EV) and section 3.2 Setting Param-
eters (with EV Counter) to adjust the resolution.
NOTE •The gage resolution has been factory-set to 1mm.
•It is not necessary to modify the resolution on the EV-
16D.
(3) Set the parameter for designating available axes according
to the number of gages to be connected.
(Refer to section 3.1 Setting Parameters (with D-EV) and
section 3.2 Setting Parameters (with EV Counter)).

NOTE Always use the RS LINK connection cable specified by
Mitutoyo. Refer to section 8.3 Optional Accessories.
(2) To link more than one counter with the RS LINK connec-
tion cables, refer to chapter 6 RS LINK FUNCTION.
TIP The D-EV will display the data of the EV Counter which
is connected to the RS LINK IN connector of the D-EV.
2.2.3 RS-232C, I/O/BCD, and RS LINK connections
The EV Counter has an RS-232C connector, I/O/BCD connec-
tor, and RS LINK connector. If these connectors are used, refer
to chapter 5 RS-232C COMMUNICA-
TION FUNCTION; chapter 6 RS LINK
FUNCTION; and chapter 7 I/O FUNC-
TION for information about cable connec-
tions.
2.2.4 Connecting the power supply and grounding
The EV Counter and D-EV do not have a power switch. Power
is supplied by connecting the power source to the +V and -V
terminals on the power inlet terminal strip.
IMPORTANT Positively ground the grounding terminal.

2 - 4 No. 99MBC034B
