INCOMING INSPECTION AND PERFORMANCE CHECK
Incoming_Inspection
Physical and Mechanical Check: If damage to the shipping cartons is evident, re-
quest that the carrier's agent be present when the instrument is unpacked. Inspect
the unit for scratches, dents, cracked lenses, broken knobs, etc., and also for
mechanical damage.
Performance Check
The electrical and mechanical performance check should be verified as soon as
possible upon receipt.
1. Initial Control Setting s(before AC_power is
qp . plieci).
Shutter - Full ccw (closed.
"Zero Control" - Centered (10-turn control, turn 10 turns in one direction than
back 5.
"Range" - "0-100".
"Sensitivity Control" - Full ccw (10-turn control).
2. Plug the G-3 primary power cord into a 105-125 VAC, 50-60Hz line. Scale
should now be illuminated. (Meter reading may or may not be on scale.) •/
3. Adjust "Zero Control" cw and ccw. Meter reading should increase and decrease
respectively. Leave with a meter reading of "20" on the 0-100 scale.
4. Turn "Range" switch to "0-20". Meter reading should increase to "20" on the
0-20 scale.
5. Turn "Range" switch to "0-100".
• 6. Insert fiber optic probe into the optical input and secure with retaining ring.
7. Turn shutter slowly from full ccw to full cw. Meter reading should
gradually
increase. If the meter goes off scale, decrease the light input entering the fiber
optic probe. Turn shutter ccw until a mid-scale reading is obtained.
8. Turn "Sensitivity Control" slow cw. Meter reading should increase. Leave
adjusted for a full scale ("100") reading.
9. Insert the supplied cable into the external output jack.
10. Connect opposite end of cable to high impedance external meter. With a full
