Teledyne HDO8000A Getting Started Manual page 9

Operational Environment
Temperature: 5° to 40° C
Humidity: Maximum relative humidity 90% for temperatures up to
31° C decreasing linearly to 50% relative humidity at 40° C
Altitudes: up to 3,000 m (at < 30° C)
Power and Grounding
The instrument operates from a single-phase, 100 to 240 Vrms (± 10%)
AC power source at 50/60 Hz (± 5%) or a 100 to 120 Vrms (± 10%) AC
power source at 400 Hz (± 5%). The instrument automatically adapts to
the line voltage. Manual voltage selection is not required.
The AC inlet ground is connected directly to the frame of the instrument.
For adequate protection against electric shock, connect to a mating outlet
with a safety ground contact.
WARNING. Interrupting the protective conductor inside or outside
the oscilloscope, or disconnecting the safety ground terminal,
creates a hazardous situation. Intentional interruption is prohibited.
Maximum power consumption with all accessories installed (e.g., active
probes, USB peripherals, digital leadset) is 550 W (550 VA)
Power consumption in Standby mode is 10 W.
Cleaning
Clean only the exterior of the oscilloscope using a damp, soft cloth. Do
not use harsh chemicals or abrasive elements. Under no circumstances
submerge the instrument or allow moisture to penetrate it. Avoid electric
shock by unplugging the power cord from the AC outlet before cleaning.
CAUTION. Do not attempt to clean internal parts.
INTRODUCTION
Calibration
The HDO8000A is calibrated at the factory prior to being shipped. This
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
HDO8000A will meet all specifications.
Warm up the HDO8000A for at least 20 minutes prior to use. During the
warm-up period, the oscilloscope will automatically initiate calibrations to
ensure that it is always calibrated.
When the oscilloscope is used outside of the factory calibration
temperature range, a user-invoked temperature dependent calibration is
recommended. There are two options for this calibration: Calibrate All or
Calibrate Current Setting.
Calibrate All - All possible combinations of vertical and horizontal settings
are calibrated at the current temperature. This calibration is valid for the
current temperature ± 5° C and takes about 50 minutes.
Calibrate Current Setting - The oscilloscope is calibrated at the current
vertical and horizontal settings. This calibration is valid for these settings
at the current temperature ± 5° C and takes under 30 seconds.
It is also recommended that the HDO8000A be calibrated when it has
been more than 1 month since the previous calibration.
CAUTION. Remove all inputs from the oscilloscope prior to
calibration.
