High Voltage Dierential Probe User Manual
DP750
1、Oveiew
Designed with unconventional appearance, the DP750 adopts the solution by building in the test
line and probe which with shielding function, integrated the interface end in a compact box, no
need to twist the cables, leads to a lower noise oor and has less inteerence.
Max 100MHz bandwidth, Max input voltage 750V, switchable 50X / 500X attenuation ratio, high
accuracy, the noise floor is low and is not affected when switching ratio, support one-press
Zero calibration, and overvoltage alarm. Support USB power supply, suitable for any brand of
oscilloscope. Support direct power supply with Micsig UPI multi-function interface oscilloscope.
Automatically matches the scope attenuation coecient without manual adjustment.
The DP750 can be widely used in the research and development, commissioning or maintenance
of switching power supplies, frequency conveers, electronic ballasts, frequency conversion home
appliances and other electrical power devices.
5、Precautions
1) Before staing the measurement, the zero point of the probe needs to be calibrated:
First sho-circuit the two input terminals, power on, press and hold the "Zero" button for 3s, the
two indicators will sta ashing at the same time, and the Zero point calibration is successful after
3s.
2) When the differential probe output is connected to the oscilloscope, the bandwidth of the
oscilloscope is required to be no less than 100MHz, and the input impedance of the channel is no
less than 1MΩ.
3) It is recommended to use it after warming up for 10 minutes to get more accurate data.
4) If there is a functional failure of the product, please contact local dealer or Micsig directly.
6、Warranty
1) The main body of this dierential probe is guaranteed for 1 year. During the product warranty
period, under normal use, the company will be responsible for free maintenance without dismantling
and repairing the fault caused by the quality of the product itself.
2) The warranty is invalid in the following cases, but maintenance seices are provided, labor costs
