Installation The weigh cells are available in various versions. If you have ordered special options, the weigh cells are equipped with the specified features at the factory. Storage and Shipping Conditions – Once the equipment has been removed from the packaging, it may lose accuracy if subjected to strong vibration. Excessively strong vibration may compromise the safety of the equipment.
Connecting the Equipment to AC Power § First, check the voltage rating and the plug design. If they do not match your local rating or standard, contact your supplier. Use only – Original Sartorius AC adapters or power supplies – AC adapters or power supplies approved by an authorized technician. § Insert the right-angle plug from the AC adapter into the jack on the electronics module and tighten the fastening screw. § Connect the equipment to AC power: Plug the AC adapter into the wall outlet (mains).
§ Remove the protective cap/transport locking device and put it in a safe place for later use. Important note: This cap is designed to protect the weigh cell. Always replace the protective cap before transporting the weigh cell and any time you pack or store it. § Place the following components onto the weigh cell in the order indicated: – Shield disk – Load receptor Important note: The GPC-26CW weigh cell comes with a 12.5 g preload weight (compensating weight).
Calibrating the GPC65-CW Weigh Cell Prior to Initial Measurement Before the evaporation trap is installed on the load receptor, the weigh cell must be calibrated at the location where it will be used and prior to the first measurement. The evaporation trap together with its lid can be used as a draft shield. $ The weigh cell is set up at the location where it will be used. $ The leveling indicator shows that the weigh cell is level. $ The weigh cell has reached operating temperature (see “Warmup Time”).
§ Place the evaporation trap on the unit. § Replace the lid. Installation is complete. § Fill the upper ring-shaped pan of the evaporation trap with water. Important note: Once the evaporation trap has been installed, allow the weighing system to rest for a moment so that the components can acclimatize to the ambient conditions. § Pull the thermal protective coverings included in the equipment supplied over the weigh cell and the evaporation trap. $ You may now begin pipetting.
Operating Design The balance consists of a weigh cell, an electronics module and a display and control unit. In addition to the choice of power supply, via AC adapter or external rechargeable battery pack, your balance also has interface ports for connecting additional devices, such as a printer, computer, or universal remote control switch, etc. The display and control unit is connected to the weigh cell. Operation of the balance follows a uniform “philosophy,” which is described in this manual.
