1.1 Basic specications (dimensions and capacity)
(1) The DP-6700 series supports two types of power sources - 6VDC (D-Series batteries) and optional
AC adaptor.
(2) The dedicated AC adaptor must be used.
NOTE: To prevent leakage of battery uid, never use the AC adaptor in combinatin with the batteries

1.3.3 How to set parameters and their meanings
The parameters are divided into 3 groups, "User Parameter," "System Parameter" and "Factory
Parameter."
In test mode, you can switch to any of the parameter modes.
In normal mode where a weight is displayed, only the user parameters can be changed. You must
turn off the power to exit parameter mode.
(1) User Parameter Mode (to congure communication functions, multifunction, and others)
Related page: Page 1-10
(2) System Parameter Mode (to set stability detection and others)
The user parameters and intended for users to change the functions of the scale according to the
user specications. The following parameters from 01 to 29 and d0 to F0 can be set, conrmed and
changed
When replacing the CPU board, make sure to check if the parameter settings are correct referring
to the parameter list.

How to Set User Parameters
Prodcedure Indication
How to switch to User Parameter Mode:
There are the following two ways to switch to user parameter mode:
In normal mode, press the key
while holding down the key; and switches to user param-
eter mode.
The user parameters can also be set in dealer parameter
mode that will be described later
See (2) System Parameter Mode (to set stability detection and oth-
ers) on Page 1-10 for how to set the dealer parameters.
Going to the next parameter:
Press key to go to the next parameter.
To change the setup vaue, enter a new value and go to the next
parameter.
Make sure to go to the next parameter to enable the new value.
If you exit before moving to the next parameter, the system dis-
cards the entered value.
Going back to the previous parameter:
To go back to the previous parameter, press the key while
holding down the key.
+1 operation for parameter value:
Press the key to increment the parameter value by 1.
If the value exceeds the setting range, the value returns to 0
-1 operation for parameter value:
Press the key to decrement the parameter value by 1 (or
increment it by -1)
If the current setup is 0, the maximum value appears.

+10 operation for parameter value:
Press the key while holding down the key to
increment the parameter value by 10.
If the setting range of the parameter is less than 10, "0000"
stays on the panel in spite of the operation.
-10 operation for parameter value:
Press the key while holding down the key to dec-
rement the parameter value by 10 (or increment it by -10).
If the settings range of the parameter is less than 10, the
maximum setup limit for the parameter stays on the panel
in spite of the operation.
(2) System Parameter Mode (to set stability detection and others)
Related page: Page 1-15 1.3.1 How to enter test mode and meanings of panel indications
System parameter mode is used to change dealer parameters such as stability detection. The following
parameters from 30 to 39 and B1 to C3 can be set, conrmed and changed.
In this mode, (1) user parameters fromt 01 to 29 can be set, conrmed and changed.
To switch to dealer parameter mode, you must switch to test mode rst. See 1.3.1 How to enter test
mode and meanings of panel indications on Page 1-5 for switching to test mode.
When you replace the CPU board, make sure to check if the parameters settings are correct, referring
to the parameter list.

Display the internal count in test mode, referring to 1.3.1 How
to enter test mode and meanings of panel indications on
Page 1-5.
When the internal count is shown on the panel, press the
key while holding down the key; and it switches to dealer
mode.
Going to the next parameter:
Press key to go to the next parameter.
To change the setup value, enter a new value and go to the
next parameter.
Make sure to go to the next parameter to enable the new value
If you exit before moving to the next parameter, the system
discards the entered value.
Going back to the previous parameter:
To go back to the previous parameter, press the key while
holding down the key.
+1 operation for parameter value:
Press the key to increment the parameter value by 1.
Keeping the key down for a while automatically increments
the parameter value by 1 continuously
If the value exceeds the setting range, the value returns to 0.

How to Set Factory Parameters
Description Indication
Display the internal count in test mode referring to 1.3.1 How
to enter test mode and meanings of panel indications on
Page 1-5. When the internal count is shown on the panel,
press the key while holding down the key; and it
switches to span adjustment mode. (See 1.3.6 Span adjust-
ment (calibration) on Page 1-22)
In span adjustment mode, press key while holding down
the key; and it switches to system parameter mode.
Going to the next parameter:
Press the key to go to the next parameter.
To change the setup value, enter a new value and go to the
next parameter. Make sure to go to the next parameter to
enable the new value. If you exit before moving to the next
parameter the system discards the enter valve
