CD-1 Indicator
1. GETTING TO KNOW YOUR CD-1 INDICATOR
1.1 Introduction
Thank you for deciding to purchase a CD-1 Indicator from Ohaus. The Ohaus CD-1 Indicator is a rugged, reliable,
electronic weight indicator designed for easy operation. The CD-1 Indicator can drive one analog load cell and provide
capacity selections up to 1,000kg.
The CD-1 Indicator operates from six Alkaline AA batteries and can also be powered externally using the supplied AC
adapter. A 0.9 inch / 2.3 centimeters high LCD provides easy visibility when working at distances from the indicator.
Two membrane switches are mounted on the front panel that enable simple set up procedures. A metal bracket with
hardware is included that permits mounting the indicator to a wall or table.
Behind your instrument stands OHAU , a leading manufacturer of precision Indicators, cales and Balances. An
Aftermarket Department with trained instrument technicians is dedicated to providing you with the fastest service pos-
sible in the event your instrument requires servicing. OHAU also has a Customer ervice Department to answer any

2.2 Selecting the Location
The CD-1 Indicator should be used in an environment which is free from vibration, temperature or humidity extremes.
These factors will affect displayed weight readings. cale bases used with the CD-1 Indicator should be located on a
stable, level surface and kept away from vibrating sources such as large machinery. Maximum accuracy will be
achieved when the working area is clean and vibration free.
2.3 Cautionar Notes
 The CD-1 Indicator must not be operated in wet or hazardous areas.
 Before connecting the AC adapter, verify that the indicated voltage corresponds to the local mains voltage.
2.4 Connecting the CD-1 Indicator to a Scale Base
The scale base is connected to the round, 4-pin connector located on the right side of the CD-1 Indicator. The mating
connector supplied in the packaging must be attached to the load cell cable. lide the connector shell over the load cell
cable. Orient as shown in the illustration. Refer to the scale base manufacturer's information to determine the proper
load cell connections. older the load cell cable to the connector contacts according to table 2-1 and refer to the the
connector illustration.
NOTE: Any extra load cell connection wires should be isolated and insulated.

3.4 Setup Procedure
The EtuP menu must be entered the first time the CD-1 Indicator is used to establish the scale base parameters.
Do not calibrate the Indicator prior to establishing parameters in the SEtuP menu.
This procedure sets up the operating parameters for the CD-1 Indicator to match the scale base.
 Press and hold the Tare Menu button. MENU is displayed
while the button is pressed and indicates CAL when released.
 Press the Tare Menu button again. EtUP is displayed.
 Press the On/Zero Off button to enter the EtUP menu. The display shows the Full cale
sub-menu F xxxx, where xxxx is the rated capacity of the scale base in kilograms. The last
selection is shown. The initial factory default setting F 1 is shown as an example.
 If the displayed setting is not the desired value, press the Tare Menu button to change to a
different setting. If the displayed setting is the desired value, press the On/Zero Off button
to store and move to the next sub-menu.
 The display shows the Graduation ize sub-menu gxxxx, where xxxx is the readability in
kilograms. The initial factory default setting is g0.001. When the Full cale value is
changed, the graduation value is automatically changed to the corresponding default value
(Refer to Table 3-1).
 If the displayed setting is not the desired value, press the Tare Menu button to change to a
different setting. If the displayed setting is the desired value, press the On/Zero Off button
to store and move to the next sub-menu.
 The display shows the Calibration Point sub-menu CPxxxx, where xxxx is the calibration
point in kilograms. The default setting is CP 1. When the Full cale value is changed, the
calibration point value is automatically changed to match the full scale value.
 If the displayed setting is not the desired value, press the Tare Menu button to change to a
different setting. If the displayed setting is the desired value, press the On/Zero Off button
to store and move to the next sub-menu. The display shows CAL ? (calibrate ?).
 After the Indicator has been properly set up to match the scale base parameters, calibrate
the unit before using. To enter calibration, press the On/Zero Off button and start at step
3 in the Calibration Procedure.
 If the menu settings were not changed, press the Tare Menu button to return to the weigh-
ing mode.

3.5 Calibration Procedure
The calibration procedure can be performed as often as necessary.
1. Make sure the scale base platform is empty, stable and level before starting calibration.
2. Press and hold the Tare Menu button. MENU is displayed while the
button is pressed and indicates CAL when released.
NOTE: The calibration process can be terminated at any time by pressing and holding the
On/Zero Off button until OFF is displayed.
3. Press the On/Zero Off button. -C- is displayed momentarily
(Indicator stores the zero load signal) followed by the calibration
weight value. CP 1 (1kg) is shown as an example.
4. Place the indicated calibration weight on the platform, then press the
On/Zero Off button. -C- is displayed (indicator stores the Cal point
load signal), followed momentarily by the indicated calibration
weight on the platform.
5. Remove the calibration weight from the scale base platform. The Indicator is now ready for
use.
