• To exit the menu during operation, press ESC located
above the soft keys.
• For a description of the operation using a USB keyboard or
a USB mouse, see section 4.3.
Setting the Offset Voltage
1. Press one of the CH1 to CH8/4 keys to select the channel.
You can select up to channel CH4 and CH8 on the DL7440 and DL7480, respectively.
2. Press the Offset soft key.
3. Turn the jog shuttle to set the offset voltage.
Resetting the Offset Voltage
4. Press RESET. The offset voltage is set to 0 V.
Explanation
The offset voltage applies to all input couplings.
Selectable Range of Offset Voltage
Voltage Axis Sensitivity (Probe = 1:1) Offset Voltage Selectable Range
2 mV/div to 50 mV/div –1.0 V to 1.0 V
0.1 V/div to 0.5 V/div –10.0 V to 10.0 V
1 V/div to 10 V/div –100.0 V to 100.0 V (except 1/V/div only for DC50Ω)
1 The resolution is 0.01 divisions. For 2 mV/div, the resolution is 0.02 mV.
2 The values are 10 times, 100 times, and 1000 times the values shown above when the probe
attenuation is 10:1, 100:1, and 1000:1, respectively. If the probe current-to-voltage
conversion ratio is 10 A: 1 V, the values are the same 10 times the values shown above with
the unit changed to A. If the ratio is 100 A: 1 V, the values are 100 times the values shown
above with the unit changed to A.
Resetting the Offset Value
Pressing the RESET key resets the offset value to 0 V.
