Unpacking:
Carefully remove the balance and the separate poise (sliding weight) from the
protective carton. You will find a slit rubber washer lodged underneath the
platform, and one rubber washer located above the pointer. The washers are to
be removed from the scale.
Set-up:
After placing the balance on a smooth, flat surface, slide the separate poise up
into the slot on the back of the center beam. Tilt poise over into place on the
beam. With all poises in zero position, the pointer should be near zero. On
applicable models, the tare poise (13) shall be at the extreme left of its bar.
.
Zeroing:
For exact zero, adjust the knurled knob which is located at the left end of the
beam. It is advisable to check the zero adjustment periodically.
Weighing:
Place the specimen on the center of the platform and proceed as follows:
1. Starting with the largest capacity beam (500 g), move the 500 g poise to the
right to the first notch which causes the pointer to drop, then, move it back one
notch, causing the pointer to rise.
2. Repeat procedure with the 100 g poise.
3. Slide the 10 g poise to the position which brings the pointer to rest at zero.
The weight of the specimen is the sum of the values of all poise positions, read
directly from the graduated beams.
