Weight (mass) values are shown using 4 digits including negative sign and decimal

places. Prompts for calibration and possible error conditions are also shown using

these digits.

1.2.2 Stable Reading Indication:

1.2.3 Low Battery Indication:

The battery symbol on the left side of the display indicates a low battery

condition. When first displayed, approximately 12 hours of operation remain.

When the battery is fully depleted, the scale will momentarily display “Lo bAt” and

shut off.

2. INSTALLATION

2.1 Package Contents

• Scale

• Power Adapter

• Instruction Manual

• Warranty Card

2.2 Location

Use the scale on a firm, steady surface. Avoid locations with excessive air current,

vibrations, heat sources, or rapid temperature changes.

2.3 Power

2.3.1 AC Power

The AC adapter (included) may be used to power the scale when battery power is

not available. Connect the AC adapter plug to the input jack. Then plug the AC

adapter into a properly grounded power outlet.

Figure 2-1. Power Connection.

2.3.2 Battery Installation (Optional)

Open the battery cover on the bottom of the scale and install three “C” size (LR14)

alkaline or rechargeable batteries into the compartment. Orient the batteries as

shown on the inside of the compartment. Close the battery cover.

NOTE: Batteries are not included.

Figure 2-2. Battery Installation.

CAUTION: Do not dispose of used batteries in domestic waste. Follow the

proper disposal or recycling requirements in accordance with local laws

and regulations.

3. OPERATION

3.1 Turning Scale On/Off

To turn the scale on, press the ON/ZERO

Off

button. The scale performs a display

test, momentarily displays the model/software version, and then enters the active

weighing mode.

To turn the scale off, press and hold ON/ZERO

Off

button until OFF is displayed.

3.2 Zero Operation

By pressing the ON/ZERO

Off

button, the scale display returns to zero. When adding

additional mass, the ON/ZERO

Off

Button may be used repeatedly until the full

capacity of the scale is reached. When a container is used, the ON/ZERO

Off

button

may be used to simulate a Tare function. Additional mass may then be added as a

EN-5Catapult 1000 Series Scales

NET weight. When removing both the sample and container from the scale, a

negative value may be displayed. Zero the scale again before subsequent usage.

NOTE: The ON/ZERO

Off

button will perform a true zero setting function when

displayed values are within +2% of full capacity. Above 2%, the range is limited to

full capacity by subtraction.

3.3 Changing Units of Measure

Press the UNITS

Cal

button to display the next available measuring unit.

3.4 Auto Shut-Off

To extend battery life, the scale will automatically turn off after approximately four

minutes of inactivity. This feature is only active during battery operation.

3.5 Dynamic Weighing

With the platform empty, short press the UNITS

Cal

button

to cycle through the units. Dynamic mode is active when

the indicator • is flashing.

Place a mass on the platform. The scale will show “-A-”.

NOTE: If using a container, press ON/ZERO

Off

to tare the

weight and return to zero.

With a mass on the platform or container, a short press of

UNITS

Cal

will start the averaging countdown from 5

seconds.

The averaged weight is then displayed. The indicator •

stops flashing when the process is complete.

The display will hold until a button is pressed.

To repeat the process press UNITS

Cal

with a mass on the

platform or container.

To Exit, remove the mass from the platform or container and

press UNITS

Cal

4. CALIBRATION

For best results, calibrate the scale at regular intervals. (Calibration weights are not

supplied with the scale.)

CAUTION

USE EXTREME CARE WHEN HANDLING CALIBRATION WEIGHTS

AS THEY ARE VERY HEAVY. IMPROPER LIFTING METHODS OR

MISUSE OF CALIBRATION WEIGHTS MAY RESULT IN PERSONAL

INJURY. MULTIPLE WEIGHTS MAY BE USED TO EQUAL THE

REQUIRED CALIBRATION WEIGHT

NOTE:

• Ensure the appropriate calibration masses are available before beginning

calibration (see Table 4-1).

• Ensure that the scale is level and stable during the entire calibration

process.

• Calibration is unavailable in Dynamic Weighing Mode.

• Allow the scale to warm up for at least 2 minutes after stabilizing

to room temperature.

• To abort calibration, press UNITS

Cal

, or power off the scale.

TABLE 4-1. CALIBRATION WEIGHTS.

Model Calibration weight (kg/lb)

C11P9 9 / 20

C11P20 20 / 40

C11P75 50 / 100

4.1 Span Calibration

Span Calibration uses two points to adjust the scale. The first point is the zero value

where there is no weight on the scale. The second point is the Span value where a

calibration mass is placed on the scale.

To select the weighing unit to be used for calibration,

press the UNITS

Cal

button until the correct unit is

displayed.

Press and hold the UNITS

Cal

button until “CAL” is

displayed.

EN-7Catapult 1000 Series Scales

With the platform empty, press the ON/ZERO

Off

button to

capture the scale zero. The display will show “-C-”.

After the zero is captured, the required span calibration

weight in the selected unit is displayed.

Place the calibration weight on the platform and press

ON/ZERO

Off

button. The display will again show “-C-”.

After span capture, the display will return to the normal

weighing mode.

NOTE: The message “CAL E” will appear if an incorrect calibration weight was

applied. Repeat the procedure using the correct calibration weight.

4.2 Calibration Locking

By use of an internal switch, the calibration function may be locked (disabled), and

unauthorized recalibration prevented.

With the scale powered off, remove the cover under the indicator by unscrewing the

two screws at the bottom.

Slide the switch on the PCB (marked SW3) to the position marked “CAL LOCK”.

Reassemble the cover.

If required, place tamper evident sealing labels over the screw holes or over the

housing edges.

If later recalibration is required, the cover will need to be reopened and the lock

switch returned to the original position.

NOTE: When the lock switch is set to the CAL LOCK position, the power-on zero

range is reduced to 10% of full capacity.

5. MAINTENANCE

Caution: before cleaning, turn off the scale, and remove the AC adapter.

5.1 Cleaning

The housing may be cleaned with a cloth dampened with a mild detergent if

necessary.

Do not use solvents, chemicals, alcohol, ammonia or abrasives to clean the

housing or control panels.

5.2 Troubleshooting

The following table lists common problems and possible causes and remedies. If

the problem persists, contact Ohaus or your authorized dealer.
