GF-Series	GF-200/300/400/600	200/300/400/600g x 0.001g
	GF-2000/3000/4000/6100	2000/3000/4000/6100g x 0.01g
	GF-6000/8000	6000/8000g x 0.1g

The GF-Series offers all the spectacular features of the GX-Series except the internal motorized calibration feature has been removed. Therefore, if you click on pages in the nav box above page 4 (accessories), 5 (display), 6 (features), 7 (ip-65 rating), 8 (detail about the sensor), or page 9 (SHS technology) it's the same for the GF-Series as the GX-Series except there is no internal calibration mass.

ISO 9000 procedures favor the calibration of balances with an external certified calibration mass. A balance with internal motorized calibration weight is a nice feature, but costly. Most balances with the internal calibration feature also offer external calibration. External calibration is vital since it is much more convenient to send out the external calibration mass for recalibration/certification verses the costly fee of having the internal calibration mass removed from the balance and sent out for re-calibration.

In addition, if you own several of the same balances just one external traceable calibration is needed for ISO compliance.

Precision Weighing Balances always recommends that you purchase the calibration mass with any balance you select. This allows you to calibrate the unit yourself without requiring the services of an outside calibration firm. Best of all calibration couldn't be simpler. Connect the AC adapter and warm up the balance with nothing on the weighing pan. Then simply turn "ON" the balance, allow the balance to go through the power-up routine and then press and hold the "CAL" until "CALout" is displayed. The display walks you through the cal procedure in less than 1 minute. The entire cal is controlled by the user-friendly keypad. The days of opening the balance and tweaking those potentiometers and trim resistors to calibrate a scale are gone with the advent of the digital circuit and EPROM technology first implemented by A&D Engineer's.

All A&D GF-Series come standard with built-in RS-232c and A&D WinCT balance communication software on CD-Rom to interface your balance with your computer.

Calibration		Calibration requires the purchase of one of the masses listed above for the specific model. The GF Series like many of the other A&D balances offers the ability to select different masses that best meets your weighing application for calibration. To learn more about the selectable calibration setting click here. We also offer a large selection of calibration masses here. If you prefer internal motorized calibration see the GX-Series.
