Operating Instructions

Safety Precautions

General Safety Instructions

Read operating instructions carefully, avoid hazardous areas, only authorized personnel to open balance.

Installation Safety

Ensure correct voltage rating for AC adapter; use caution with RS-232 cables due to potential pin assignment mismatches.

Equipment Supplied

Getting Started

Storage and Shipping Conditions

Do not expose balance to extreme temperatures, moisture, shocks, blows, or vibration.

Balance Unpacking and Inspection

Check for external damage immediately after unpacking. Refer to 'Care and Maintenance' for damage.

Installation Location Requirements

Choose a location not subject to heat, drafts, extreme vibrations, or excessive moisture.

Balance Conditioning

Condition balance for 2 hours at room temperature after transfer to warmer areas to prevent condensation.

EU Legal Metrology Seal

Verified balances of accuracy class II require a control seal; breaking it voids verification.

Installation

Model CPA2P Installation

Remove adhesive tape from chamber doors and place interior draft shield and weighing pan.

Model CPA2P-F Installation

Install filter pan or standard weighing pan, interior draft shield, and spacer ring as applicable.

Analytical Draft Shield Setup

Ensure sliding lock device on draft shield is open (right); position shield carefully on balance.

Connecting Balances

Connecting to Electronics Box

Plug the male connector on the cable into the female connector on the electronics box. Do not exchange components.

3-Sided Draft Shield Installation

Place draft shield with cover opening in front on the right; turn clockwise until firmly in position.

Installing Weighing Pans

Rectangular Pan (≤ 10 kg)

Place weighing pan and gem tray (if applicable) on balance/scale.

Rectangular Pan (> 10 kg)

Place the weighing pan on the balance.

Connecting Power

Connecting to AC Power

Use only original Sartorius equipment; connect AC adapter to balance/electronics and then to outlet.

AC Adapter with Country-Specific Cord

Select country-specific power cord, connect to AC adapter, then plug into wall outlet.

Connecting Peripherals and Setup

Connecting Electronic Peripherals

Unplug balance from AC power before connecting/disconnecting peripheral devices.

Balance Warmup Time

Allow specified warmup time (e.g., 4 hours for CPA2P) for exact results after power connection.

Antitheft Locking Device

Fasten a chain or lock to the lug on the rear panel for securing the balance.

Leveling the Balance

Leveling Balances (≤ 10 kg)

Retract rear feet; adjust front feet until bubble is centered in level indicator.

Leveling Balances (> 10 kg)
