EN-12 PX Series Balance 4. Confirm the weighing time by pressing Yes, and the message "Ready" will display at the lower left of the screen. 5. Place the dynamic object on the pan. The balance begins a countdown (averaging process). During the countdown, the screen shows the time remaining. - Page 15 When making density measurements, the material should weigh at least 10.0 mg on an analytical balance and 100 mg on a precision balance. Balance Preparation with Ohaus Density Kit (Optional) Allow the balance to warm up sufficiently before making measurements.
- Page 16 EN-14 PX Series Balance Place the Support into position over the bracket making sure the Support does not make contact with the Bracket as shown in illustration. Install beaker on support as shown. NOTE: Beaker and thermometer are not supplied as part of the density kit. The density Q is the quotient of the mass m and the volume V.
- Page 17 PX Series Balance EN-15 Place the solid in the Weighing Pan on the Weigh Below Hook in the liquid as shown. Ensure that there are no air bubbles on the solid to be weighed. Close the draft shield doors and weigh the solid (buoyancy P). The display indicates the density in grams/cc.
