(2-2) Setting the output mode at contact OFF in external synchronized operation (see
5.2.16)
The current output mode at contact OFF in external synchronized operation is
displayed in the initial menu "ho: 4-20mA IN [EXT]" of "11: OTHERS". To make
changes, it is necessary to press the [SET] key and place the software in the setup
state. Each time the [UP] or [DN] key is pressed, the mode display is switched
around from "LAST" (immediately preceding value), through "4mA" to "TEST" (the
simulated output value in setting mode). Press the [SET] key on the display in the
selected mode to confirm. The screen is returned to that of the immediately preceding
menu screen. Make sure that the resetting is done correctly.
(2-3) Returning to the measuring mode
Press the [ESC] key twice to return to the initial menu and return from the setting
mode to the measuring mode to resume the normal measurement.
(3) Setting the ope ration mode
(3-1) Selecting the operation mode change menu (see Subsection 5.2.6)
In the initial menu, use the [→] key to move the cursor of the LCD indicator to the
menu number "3" of "3: MEASURING MODE" and then press the [SET] key to get
into the operation mode menu.
(3-2) Verifying and setting the operation mode
The current operation mode is displayed at "DATA" of the LCD indicator . "CONT"
refers to the mode of taking measures continuously without relying on the status of the
external contact signal, whereas "EXT" refers to the external synchronized operation
mode. If the current setting is "CONT," press the [SET] key to get into the setup
screen of operation mode; press the [UP] or [DN] key to switch the set value of the
operation mode to "EXT"; and press the [SET] key to confirm. The screen is returned

(4) Starting the external synchronized operation
With the settings above, measurement ON/OFF are proceeded with as shown in Fig.6.7.1 in
accordance with external synchronized contact signal ON/OFF.
6.8 Functions Related to Operation
To enable you to use the Density Meter Type LQ500 more appropriately in various processes and
situations, the device is equipped with various functions including the moving average, the
change-rate limit, the electric conductivity correction, the additive correction, the linearizer and the
density multiplier switching by external signals. Make settings necessary for using these functions
appropriately where necessary. For details, please refer to Chapter 10.
