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:
A *will appear in the lower left corner of the display to indicate when the reading is
stable.

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.

Set CAL LOCK to OFF (see section
4.2)
Move the scale to suitable location
Use correct calibration mass
Scale displays “Lo
bAt”
Battery is discharged Connect power or change the
batteries
Scale displays “Lo
Line”
