Micsig DP750-100 High Voltage Differential Probe User Manual

Micsig DP750-100 High Voltage Differential Probe

Overview

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 floor and has less interference.
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 coefficient without manual adjustment.
The DP750 can be widely used in the research and development, commissioning or maintenance of switching power supplies, frequency converters, electronic ballasts, frequency conversion home appliances and other electrical power devices.

Precautions

1. Before starting the measurement, the zero point of the probe needs to be calibrated:
   First short-circuit the two input terminals, power on, press and hold the “Zero” button for 3s, the two indicators will start flashing 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.
