Cleaning
Clean the outside of the WaveSurfer 3000z using a soft cloth moistened
with water or isopropyl alcohol solution. Do not use harsh or abrasive
cleansers. Dry thoroughly before using. Do not submerge the instrument
or allow moisture to penetrate it.
Fuse Replacement
Disconnect the power cord before inspecting or replacing the fuse. Open
the fuse holder (located at the rear of the instrument below the AC power
inlet) using a small, flat-bladed screwdriver. Replace the old fuse with a
new 5 x 20 mm T-rated 3.15 A/250 V fuse. Close the fuse holder before
powering on.
WARNING. For continued fire protection at all line voltages, replace
the fuse with one of the specified type and rating only. Always
disconnect the power cord before replacing the fuse.
Calibration
The WaveSurfer 3000z is calibrated at the factory prior to being shipped.
The calibration is run at 23 °C (± 2 °C) and is valid for temperatures ± 5 °C
of the original calibration temperature. Within this temperature range, the
WaveSurfer 3000z will meet all specifications once warmed up.
Warm up the WaveSurfer 3000z for at least 20 minutes prior to each use
so it can reach a stable operating temperature. Specifications are not
guaranteed during the warm up period.
Whenever the oscilloscope is used in an environment ± 5 °C from
the original calibration temperature, or when it has been more than
one month since the previous calibration, manual calibration is
recommended. There are two calibration routines for selection:
Calibrate All calibrates all possible combinations of vertical and
horizontal settings at the current temperature. This calibration is valid for
the current temperature ± 5 °C and takes about 45 minutes.
Calibrate Current Setting calibrates at the current vertical and horizontal
setting. This calibration is valid at this setting only for the current
temperature ± 5 °C and takes under 30 seconds.
From the menu bar, choose Utilities > Preference Setup > Calibration to
run the calibration.
CAUTION. Remove all inputs from the oscilloscope prior to
performing calibration.
Schedule factory calibration once per year. Contact your local Teledyne
LeCroy office for service.
