INSTALLATION & OVERVIEW
Remember that the installer is ultimately responsible to assure that an installation will be and
remain safe and operable under the specific conditions encountered.
Installation of C705P force data instrument
Find a suitable location for the instrument and use the included bracket to mount the unit to a wall or
table. Use this handy guide for mounting the bracket to a wall or table:
CONNECTIONS
The rear cover must first be removed to make the appropriate connections to the weigh platform, etc. To
remove the rear cover, simply remove the screws that secure it to the enclosure and set aside.
Caution! Disconnect power source from instrument prior to removing rear cover.
Caution! Disconnect leads from rechargeable battery (if installed) to avoid shorts!
Force sensor Connections
Connect your shielded force sensor cable to terminal block J1 using the table below. All terminals are
labeled for function.
TIP: You should have the color codes handy for your force sensor before doing so.
Force sensor Terminal Block J1

NOTE1: Use G11 to configure for 4-wire or 6-wire force sensors
NOTE2: Pins 1 and 2 are for DC power input (V+ and V– respectively) …
NOTE3: There are two configurations for J1, as shown above, and differing only in the location of the
force sensor shield wire connection (GND)
Power Connections (AC version)
The C705P instrument ships with a pre-installed AC line cord. It has been pre-wired to Terminal Block J1
at the factory. Simply plug the unit into a standard wall outlet.
USB Port
The external USB port is used for communication and updating of the firmware. Consult factory for use.
Getting Started
1. Press and hold the ON key on the force instrument for two seconds.
After a brief initialization period, the instrument will revert to a zero (“0”) force display.
Your instrument is now ready for configuration and system calibration.

SYSTEM CONFIGURATION
1.1 Configuration Menus
The C705P instrument contains five menus to configure the calibration system:
1. Setup (“F”) Menu –Configures all scaling parameters, including calibration procedures. All
Profiles [PF1-PF5]
2. Polynomial Setup (“P”) Menu –Configures all Polynomials. All Profiles [PF1-PF5]
3. General Setup (“G”) Menu –Configures general measurement parameters. Settings apply to all
Profiles [PF1-PF5]
4. User1 (“A1”) Menu –Configures COM1 communication parameters and other misc. parameters,
e.g., automatic turn off and hold mode.
5. User2 (“A2”) Menu –Configures COM2 communication parameters.
The configuration menus are laid out in the following vertical arrangement:
• Top [Menu selection] level [Note: some menus may have a secondary top level, e.g., -F- and F-
PF 1
• Parameter level
• Selection level (or function level, e.g., span calibration)
Please review the following chart to get a feel for how to navigate among the various menus and parameters.
NOTE: The -C- menu appears in place of the -B- menu for cabled systems.

1.2 Entering the Setup (“F”) Configuration Menu
Note: This configuration menu has five (5) secondary-top levels - PF 1 to PF 5 - corresponding to the give
(5) profiles (PF-1 to PF-5). Instructions are identical for each profile.
1. Switch off the instrument by pressing the MENU/OFF key (“oFF”) followed by the PEAK/FREEZE
key.
2. Press and hold the ON key until the instrument beeps and starts to boot up.
3. During the countdown phase (“555555, 444444”, etc.) press and hold the MENU/OFF key until
the “Set?” message is displayed.
4. Press the PEAK/FREEZE button while “Set?” is being displayed. The instrument displays
“-F-“.
5. Scroll down one level by using the ZERO (down) key to reach the secondary top level. The
instrument shows “F-PF 1”.
6. Move from one profile [PF 1 to PF 5] to the next by using the PROFILE (left) or DATA (right) keys.
For example, to go from F-PF 1 to F-PF 2, press the DATA key. To go from F-PF 2 back to F-PF
1, press the PROFILE key.
7. Scroll down using the ZERO (down) key to reach the parameter level. The instrument shows
“PF1-F 1”.
8. Move from one “PF1-F” menu parameter to the next by using the PROFILE (left) or DATA (right)
keys. For example, to go from PF1-F 1 to PF1-F 10, press the DATA key. To go from F- PF1-F 10
back to PF1-F 1, press the PROFILE key.
9. Once you have arrived at the proper “PF1-F” menu parameter, e.g., “PF1-F 1”, press the
ZERO (down) key once to arrive at the selection level. The instrument displays the current
parameter setting.
10. If there is a selection list, scroll thru the available parameter settings, use the PROFILE (left) or
DATA (right) keys. Otherwise, use the arrow keys to adjust the displayed value to the new value.
11. Once the setting you want is displayed on the screen, press the PEAK/FREEZE (set) key to save
this value and revert up to the parameter level, e.g., “PF1-F 1”.
1.3 Leaving the Setup (“F”) Configuration Menu
1. While on any level except the selection level, press the MENU/OFF key.
