Operation
Instrument activation
After reading and performing the procedures in Preparations on page 2-1, the fol-
lowing steps should be taken to activate the instrument:
l
Connect the supplied power cord to the power input connector at the rear of the
instrument. A grounded three prong wall connector is required for electrical ser-
vice.
l
Move the "ON/OFF" switch to "ON".
l
Press the "Lamp Start" button ( Figure 2-2 on page 2-3) firmly and release after
holding for approximately 2 seconds. If the fluorescent tube does not illuminate,
repeat the procedure.
l
Press the Zero button to clear the display ( Figure 2-2 on page 2-3).
Display response
The display will rapidly accumulate numbers when the "ON/OFF" switch is placed
in the "ON" position. This accumulation will continue until the fluorescent tube is
activated. If numbers continue to accumulate, refer to
Troubleshooting on page 6-1
for possible remedies.
Data accumulation may continue to occur if the fluorescent tube output is not suf-
ficient, such as initial starting in extremely cold conditions. Excessively low line
voltage is also a cause for continued rapid spurious counting.
