1. GETTING TO KNOW YOUR INDICATOR
1.1 Introduction
Thank you for deciding to purchase a CD-11 Indicator from Ohaus. The Ohaus CD-11 Indicator is a rugged, reliable,
electronic weight indicator designed for easy operation. The CD-11 Indicator has been NTEP tested and complies
with Class III and IIIL requirements of NIST HB44 for 1:5000 performance in pounds, kilograms, or grams. The CD-
11 Indicator can drive up to four 350 ohm load cells and provides capacity selections up to 20,000 lb/kg with a
maximum resolution of 1:20,000.
The CD-11 operates from six Alkaline “C” batteries and can also be powered externally using the AC adapter sup-
plied. A six digit LCD display is 1.0 inches/2.5 centimeters in height provides easy visibility when working at dis-
tances from the indicator. Four switches mounted on the front panel enable simple set up procedures. A menu
lockout switch can be set to lock out various functions of the indicator to prevent settings from being changed. An
RS232 Interface is built in. Accessories are available which permit the Indicator to be table, wall, or tower mounted.
Behind your instrument stands OHAUS, a leading manufacturer of precision Indicators, Scales and Balances. An
Aftermarket Department with trained instrument technicians is dedicated to providing you with the fastest service
possible in the event your instrument requires servicing. OHAUS also has a Customer Service Department to
answer any inquiries regarding applications and accessories.

before installation and operation.

2.2 Selecting the Location
The Indicator should be used in an environment which is free from corrosives, vibration, temperature or humidity
extremes. These factors will affect displayed weight readings. Scale bases used with the 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 area is clean and vibration free.
2.3 Connecting the Indicator to a Scale Base
• Turn the Indicator over and using a screw driver, remove the four screws which secure the rear cover. Two
screws are under the battery box's cap.
• Remove the rear cover.
• Remove batteries if installed.
• Pass the load cell cable through the liquid tight
connector on the left side of the housing.
• Refer to the color code of the load cell cable and
connect the wires to Terminal Strip J4. Tighten all
screws securely. The connections are shown for a
6 wire cable. When a 4 wire cable is used,
The Jump 1 and Jump 2 jumpers on the PC board
must be positioned as shown in the illustration.
For obtaining better performance, it is recom-
mended to keep both JUMP 1 and JUMP 2 jumpers
open when a 6-wire load cell is connected to the
CD-11.
