[(193)10A RedBlue][(10)10A RedRed][(366)50A RedRed-Shunt][(175)50A RedBlue-Shunt][(173)100A RedRed-Shunt][(350852)100A RedBlue-Shunt]Purchase note:
1. The voltage range of this product is 0-200V, and the current range can be selected according to your actual needs.
2.10A meter head uses built-in shunt, no need to add shunt
3. The 50A 100A meter head must be connected to a shunt before it can be used. Even if the 1A current is tested, a shunt must be added (novice note). If you don't have a shunt at home, you need to purchase our shunt to use!
4. Voltage red + current red / voltage red + current blue
Wiring mode: The connection mode of this meter is flexible. Either share the power supply with the device under test, or use an independent power supply, just change the wiring!
Power supply: 3.8-30V DC power supply with reverse connection protection (but the reverse connection cannot exceed 30V)
Power consumption of this machine: <=20MA, very power saving
Refresh speed: about 3 times/S
Current internal resistance: 10A/5 milliohms, 50A/1.5 milliohms, 100A/0.75 milliohms
Voltage internal resistance: 200V/800K
Test accuracy: Voltage: range X0.08%+2 words Current: range X0.08%+2 words Range selection technique: The error size is closely related to the range, and a small range can get a smaller error
Display color: Specification: voltage red + current red Second specification: voltage red + current blue
Dimensions: 48mm*29mm*20mm (plastic shell size)
Hole size: 45.5mm*26mm
The control part of this voltmeter uses a powerful CPU core. The number of CPU pins can reach as many as 20 pins. The performance exceeds the general 16-pin or 18-pin domestic or Taiwanese one-time programming chip. This chip can be programmed repeatedly. Therefore, each voltmeter can be independently debugged to achieve high accuracy, which is not achieved by ordinary one-time single-chip microcomputers! The accuracy of the voltmeter surpasses ordinary low-cost multimeters (for example, tens of yuan per meter, the accuracy of some domestic brands of multimeters is still very low, please do not use them as a standard comparison), the multimeters used in our shop are all American brand multimeters.
