Precautions (DATAMAN 520 and 570 series)
Please follow these recommendations to avoid any possible problems that might occur
while using the oscilloscope of DATAMAN 520 or 570 series:
- read the User’s Guide
- always connect the device using the cable, which is the part of package. If it is not
possible, always use a USB 2.0 specification cable.
- never connect a signal with absolute voltage higher than 200V to the measuring
inputs. This value is valid for frequencies lower than 100kHz. Over this frequency,
the voltage lowers with raising frequency. For example frequency 200kHz of 100V,
400kHz of 50V is the limit. However we do not recommend connecting a voltage
higher than 50V, because touching it can be dangerous.
- never connect a voltage lower than –10V and higher than +13V to the external
triggering input (frequency lower than 20kHz). Over 20kHz, voltage lower than -0.5V
or higher than +4V is not recommended.
- never connect a voltage to the oscilloscope ground, it may result in device or
computer damage
- never disassemble the device, since there are no user serviceable parts inside
- touching parts under test with voltage higher than 50V can be dangerous for your
health
Precautions (DATAMAN 770 series)
Please follow these recommendations to avoid any possible problems that might occur
while using the oscilloscope:
- read the User’s Guide
- always connect device using USB cable, which is the part of the package.
- never connect voltage higher than 200Vp between the measuring ground and the
input. This value is valid for frequencies lower than 100 kHz. Over this frequency, the
