1. Introduction
This manual describes how the GXM-04, GXM-06 (Comparator output, analog voltage output)
works and how to get the most out of it in terms of performance. Read this manual thoroughly
before using and keep it at hand for future reference.
2. Features
The following options can be used for the GX-M series and GF-M series.
GXM-04 Comparator output (with buzzer) / External contact input x 2 / RS-232C
GXM-06 Analog voltage output / RS-232C
GXM-04: Comparator output / External contact input
The GXM-04 can compare the weighing value and preset threshold values and can output the
result to the contact output.
The GXM-04 is equipped with six contact outputs:"HH", "HI", "OK", "LO", "LL" of the
comparison output and "READY" output to indicate the status of the balance.
3-stage comparison or 5-stage comparison can be selected.
The GXM-04 can sound a buzzer according to the comparison result.
The GXA-04 is equipped with external control input terminals that can make the RE-ZERO
and PRINT key operations. An optional foot switch (AX-SW137-PRINT, AX-SW137-RE-
ZERO) can be used.
GXM-06: Analog voltage output
The GXM-06 can output analog voltage in the following modes :
"mode where the specified digits of the weighing value are converted to voltage" and
"mode where weighing value is converted to voltage in range between gross zero or net zero
and full scale".
The voltage output range can be selected using the "0V /0.2V " switch on the panel.
It can be selected "0 to 1V" range and "0.2V to 1V" range. The factory setting is "0 to 1V" range.

4. Installing the Option
Caution Disconnect the AC adaptor before installing the option to the balance.
Installing the option board to the balance
Install the GXM-04 and GXM-06 according to the following procedure.
(The installation procedure of the GXM-04 and GXM-06 is the same.)
Step1 Remove the two screws from the panel and remove the
RS-232C / USB board from the balance.
Step2 Pull gently and remove the two cables from
the RS-232C / USB board.
Step3 Insert the two cables into the sockets of the GXM-06 board.
Step4 Insert the rubber packing and plug the GXM-06
into the balance.
Screw the panel of GXM-06.
Caution
When inserting the GXM-06, pay attention to the top and bottom orientation of the board.
The rubber packing has a deep groove on the balance side.

5. Function Table of Balance
The function table stores parameters that specify how to operate the balance, and it is used to
mointor or update those parameters. These parameters are stored in memory even if the AC
adaptor is removed and are retained until overwritten. Balance operations are specified by this
table when using the GXA-04 and GXA-06. The table menu consists of two layers as shown
in the diagram below. The first layer is the “Class” and the second layer is the “Item”. Each item
stores a "parameter". The last displayed parameter is in effect. After the
PRINT key is pressed, these updated parameters are applied to operations of the balance.
Example of settings and menu structure
Example : Set to " Center value using sample weight input " of " Input method " in " Comparator ".
Caution
The balance may not function properly, depending on the settings and the operating
environment. Be sure to set parameters correctly.
5.1. Operation Keys and Display of Function Table
The 〇indicates that the parameter displayed is in effect.
Enters the function table when pressed and held in the weighing mode.
Selects the class or item in the function table.
Changes the parameter.
Moves to an item in the class when a class is displayed.
Stores the new parameter and displays the next class when an item is displayed.
Cancels new parameter and displays the next class when an item is displayed.
Exits the function table and returns to the weighing mode when a class is displayed.
