RIDSDALE DIGITAL BALANCE (cont’d)CALIBRATION** PLEASE NOTE: Calibration weights are NOT supplied. All balances are factory calibrated andready to operate. Calibration weights may be purchased separately ifrequired.IMPORTANT: The calibration procedure is described below. Only use the calibrationweights provided or OIML Class weights. Calibration is always recommended when first using thebalance or after the unit has been moved or subjected to an extreme change in temperature.Always perform the calibration procedure AFTER the unit has been allowed to warm up properly (atleast 30 minutes). It is also recommended to re-calibrate the unit periodically during long periods ofuse and always to start a procedure by taring the unit to re-zero the balance.External calibration is performed through use of the keypad controls and proper calibration weights.Internal factory calibration is preset and performed by accessing internal components. Access tointernal components by other than a factory authorised technician will void warranty coverage of thisunit.Calibration Procedure:(a)(b)(c)After allowing unit to warm for 30 minutes, remove all items from the tray top and tare thebalance.After observing a stable ZERO with a stable arrow in the (g) gram mode, press and hold theCAL/MODE button until calibration weight value appears on the display.Gently place the correct calibration weight as provided (or equivalent OIML Class Weights)onto the tray top.(d) The + sign will disappear. Wait approximately ten seconds as the unit performs internalcalibration.IMPORTANT – Do not disturb the balance during this time. Avoid vibration and air currents.(e)(f)When calibration is complete the unit will beep, correct calibration weight value willdisappear for one second then reappear as an active weight value. The balance is nowcalibrated.Remove calibration weight and press the TARE button to reset the zero point. NOTE: Ifcalibration weight value remains on the LCD display, an improper calibration weight hasbeen used. Remove improper weight and repeat calibration procedure with correct weight.37
RIDSDALE-DIETERT (<strong>AFS</strong>)LABORATORY SAND RAMMER (TYPE ‘N’)IGENERAL PRINCIPLESThis machine is designed for preparing <strong>AFS</strong> standard test specimens for the determinationof compression, tensile, transverse, shear and splitting strength by compacting a predeterminedweight of sand in a tube, or a core box of the required shape. This is achievedby dropping a known weight a fixed distance, and using the energy produced to compact thesand.38
