Acquire the zero input data
11 Disconnect the power supply from the channel input.
22 Press the Chan key. Move the cursor to the V/Div field and press the Select key.
33 Press the blue shift key, then press the Run key. After approximately 15 seconds
(averaging complete), press the Stop key. Read the voltage from the Markers voltage
field (0.00 V ± 320 mV) and enter the value in the performance test record.
44 Use the RPG knob to dial in 1 V/Div. Press the blue shift key, then press the Run key.
After approximately 15 seconds (averaging complete), press the Stop key. Read the
voltage from the Markers voltage field (0.00 V ± 80 mV) and enter the value in the
performance test record.
55 Use the RPG knob to dial in 100 mV/Div. Press the blue shift key, then press the Run
key. After approximately 15 seconds (averaging complete), press the Stop key.
Read the voltage from the Markers voltage field (0.00 V ± 8 mV) and enter the value
in the performance test record.
66 Use the RPG knob to dial in 10 mV/Div. Press the blue shift key, then press the Run
key. After approximately 15 seconds (averaging complete), press the Stop key.
Read the voltage from the Markers voltage field (0.00 V ± 800 µV) and enter the
value in the performance test record.
