NOTE
(d) Turn arrest-release lever to stop or locked position.
(e) Rotate STANDARD WEIGHT 1 GM knob so that 1 GM standard is applied
to balance.
(f) Release beam with arrest release lever (fully ccw).
(g) Press CALIBRATE pushbutton momentarily. The indicator will read .000-
OVER.
NOTE
and number displayed may be .999-IN RANGE, .000-OVER,
.001-OVER.
NOTE
Pan must be located before placing or removing weights.
(h) Turn arrest-release lever cw to stop or locked position and rotate
STANDARD WEIGHT 1 GM knob to remove 1 GM standard from balance.
(4) Connect digital voltmeter (A4) to blue and green wires on output terminals or
connecting plug of TI transducer, using test lead (B1). (Terminal strip is located in TI beam
chamber). If digital voltmeter does not indicate between 50 and 100 mV, perform b(1)
below.
(5) Turn control knob on side of TI until yellow strip is visible for 1 gram standard
on beam. If digital voltmeter does not indicate between 800 and 1100 mV, perform b(2)
below.
(6) Lift TI pan upward against stop. Digital voltmeter will indicate at least 100 mV
less than value observed in (4) above.
(7) Press pan downward to stop. Digital voltmeter will indicate at least 100 mV
more than value observed in (5) above.
(8) Dial in weight value on balance corresponding to standard weight value, and
