Start Up
To properly install and power on the oscilloscope, perform this procedure.
1. Check that you have the proper electrical connections. The rear label lists
power requirements for all possible voltage inputs.
2. Check the fuse to be sure it is the proper type and rating (Figure 1–2).
TDS 300 Series oscilloscopes are shipped with a UL-approved fuse installed.
Fuse specifications are as follows:
5 mm × 20 mm, time-lag, 3.15 A, 250 V, or
1.25 in × 0.25 in, time-lag, 3 A, 250 V
3. Connect the proper power cord from the rear-panel power connector
(Figure 1–2) to the power system. Use the power cord clamp to secure the
cord to the rear panel.
4. Leave space for cooling. Do this by verifying that the air-intake and exhaust
holes on the sides and bottom of the cabinet (where the fan operates) are free
of any airflow obstructions. Leave at least 5.1 cm (2 in) free on each side.
5. Press the ON/STBY button to power up the oscilloscope (see Figure 1–1).
