CD Indicators 1. GETTING TO KNOW YOUR INDICATOR 1.1 Introduction Thank you for deciding to purchase a CD-31/CD-33 Indicator from Ohaus. It offers a high level of operating convenience and useful functions to make accurate measurements. A unique LCD panel has a large 7 digit, 7 segment display which indicates the weight value of an item being measured and a 7 digit British Flag display (14 segments) which spells out items selected in the submenus.
CD Indicators 2.3 Connecting the Indicator to a Scale Base • Turn the Indicator over. NOTE:Check the wiring instructions of your scale base. • The Terminal Block located at the left side of the access area is used to connect a scale base using a 4-wire cable and ground. If a 6-wire cable is supplied with the scale base, tie the +SENSE and +EXC leads together and connect to the +EXC connector. Tie the -SENSE and -EXC leads together and connect it to the -EXC connector on the Indicator.
CD Indicators 2.5 Connecting Power Connect the AC Adapter supplied to the connector located at the bottom of the Indicator. Route the wire from the AC Adapter through the channel in the bottom of the Indicator. This will relieve stress on the connector and hold the wire in place. 2.5.1 Cautionary Notes • Models CD-31 and CD-33 Indicators must not be operated in hazardous areas. • Before connecting the AC adapter, verify that the voltage printed on it corresponds to the local mains voltage.
CD Indicators 2.6 Scale Base Setup In this section, you will enter the menu for the first time. Do not worry if you are unfamiliar with the function of the buttons on the panel, the display provides the necessary coaching as you go along. Before the Indicator can be used, the parameters for the scale base being used with the Indicator must be set first in order to calibrate and perform any functions.

CD Indicators 4. OPERATING YOUR INDICATOR 4.1 Calibration Model CD-31 and CD-33 Indicators offer a choice of four calibration methods: Span, User, Linearity, and CalTestTM. • Span - Span calibration ensures that the Indicator reads correctly within specifications using a weight value of 100% of capacity. • User - User calibration is a method where the Indicator can be calibrated using a mass between 10% and 100% of capacity and by entering that numeric value into the Indicator.
CD Indicators 4.1.1 Span Calibration Span calibration requires a mass equal to 100% of the scale base capacity. Procedure • Press the Setup button, SCALE is displayed. • Press button until CAL is displayed. • Press Enter button, CAL TYPE is displayed. • Press Enter button, CAL TYPE SPAN is displayed. • Press Enter button, CLR PAN is displayed. Clear the pan. • Press Enter button, WORKING is momentarily displayed, then PUT WT is displayed (capacity of base) on the pan.
CD Indicators 4.1.2 User Calibration User calibration is used when it is desired to calibrate the Indicator using a mass of known value from 10% to 100% of the capacity of the scale base. To use this calibration feature, proceed as follows: Procedure • Press the Setup button, SCALE is displayed. • Press button UNTIL CAL is displayed. • Press Enter button, CAL TYPE is displayed. • Press Enter button, SPAN is displayed. • Press button to select user calibration. CAL TYPE USEr is displayed.
CD Indicators 4.1.3 Linearity Calibration Linearity calibration utilizes three calibration points; one at zero, center span and full span. This method minimizes deviation between actual and displayed weights within the Indicator's weighing range. Three weight values are used; zero, a weight value at or near midpoint of the Indicator's weighing range and a weight value at specified capacity. Sample display illustrates a 40 kg scale base. Procedure • Press the Setup button, SCALE is displayed.
CD Indicators 4.1.4 Calibration Test Calibration test feature allows a check of a known calibration mass against the last stored calibration information in the indicator. Sample display illustrates a 40 kg scale base using a 10kg mass. Procedure • Press the Setup button, SCALE is displayed. • Press button UNTIL CAL is displayed. • Press Enter button, CAL TYPE is displayed. • Press Enter button, SPAN is displayed. • Press button to select calibration test,CAL TYPE CALtESt is displayed.
CD Indicators 4.1.5 Calibration GMP Printout If any option in the GMP Set Menu is turned On, GMP automatically prints data after calibration is completed.

CD Indicators 4.2 Weighing The Indicator is shipped with kilograms only enabled. When the Indicator is to be used with other Type Approved/Legal for Trade units of measure, the desired unit must be enabled. Refer to paragraph 3.9 to enable other measuring units. The Indicator is equipped with a G/N/T button which allows the viewing of gross weight, net weight and tare weight. A Tare button allows taring the weight of container, and a separate >0< zero button, zero's the Indicator display reading.
CD Indicators 4.2.2 Preset Taring Preset taring is used to enter a tared weight via the numerical keypad. If a container's weight is known, the Indicator may be preset using the numerical keypad to enter the weight. When using this feature, a time constraint of 4 seconds is imposed to start entering data, otherwise the Indicator defaults back to a weighing mode. Procedure • Press >0< button with no load on the pan to set the Indicator reading to zero.
CD Indicators 4.3 Percent Weighing Percent Weighing is enabled only when Percent is turned ON in the Mode submenu under Setup. Percent weighing permits you to place a reference load on the pan; then view other loads as a percentage of the reference. The load you place on the pan as a reference may be displayed as any percentage you select from 5% to 100% (in 1% increments). 100% does not necessarily have to represent the reference load.
CD Indicators 4.4 Parts Counting Parts Counting is enabled only when Count is turned ON in the Mode submenu under Setup and selected with the Mode button. In the parts counting mode, the Indicator displays the quantity of parts you place on the pan. Since the Indicator determines the quantity based on the average weight of a single part, all parts must be reasonably uniform in weight. Procedure • Press the Mode button. • Press or button until COUNT is displayed.
CD Indicators 4.5 Animal Weighing Animal Weighing is enabled only when Animal is turned ON in the Mode submenu under Setup. Procedure • Press the Mode button, WEIGH is displayed. • Press or button until ANIMAL is displayed. • Press Enter button to continue, LEVEL is displayed. • Press or button to change animal weighing level, 0, 1, 2 or 3. 0 level represents an inactive subject, 3 is used for a very active subject. • Press Enter button to continue, AUTO is displayed.
CD Indicators 4.6 Checkweigh Checkweigh is enabled only when Checkweigh is turned ON in the Mode submenu under setup. Checkweigh permits entering a minimum weight value and a maximum weight value though the numerical keypad or arrow buttons. You can establish minimum and maximum values for repeitive weighing of identical objects. This is suited for production where a large number of items have to be checked against preset parameters. Procedure • Press the Mode button, WEIGH is displayed.
CD Indicators 4.7 Printing Data Printing data to an external computer or printer requires that the communications parameters in the Setup menu, Print options and communication parameters be set first. Refer to paragraph 3 Setting Up Your Indicator. When time, date, GMP Data, Print and RS232 data is set, the printout data will reflect whatever parameters are turned on. Procedure • Press the Print button. Printing to an external printer or computer will occur each time the Print button is pressed.
