Product Introduction: 6L2 DC Ammeter Voltmeter
DC ammeter voltmeter introduce：
2.The accuracy of the digital display instrument is divided into 0.1, 0.2, 0.5, 1.0, 1.5, 2.5, 5.0 seven grades. The meaning of this grade refers to the error percentage of the full scale of the instrument. For example, our product AC ammeter grade is 0.5 and the input current is 5A. The meaning of 0.5 here is that when the ammeter is input 5A, its large error will not exceed 0.5 percent
2.Digital display table and analog table difference digital table advantage reading precision, high precision analog table advantages can be measured according to the swing of the pointer, see the change trend and range of the measured, so there is also a digital display instrument with light column, in order to achieve this function of the analog table
3.The power supply of the instrument is generally divided into three kinds: transformer power supply, switching power supply and battery power supply. There are three kinds of AC220V 380V AC/DC85-265V available for users to choose from
4. Classification of input measurement signals Input measurement signals are generally divided into AC signals and DC signals.
5. Difference between true RMS value and average value Compared with other digital display instruments that display average value, the value displayed by our instrument is true RMS value, which has the characteristics of strong anti-interference ability, anti-harmonic and frequency change.
6. Appearance size Our digital display table appearance size: 48*48 to 120*120 full series.
7. Additional functions In addition to the ordinary measurement functions, the instrument can also provide customers with additional modules. 1. The communication module supports RS-485 modubus RTU protocol. 2. Converter module 4-20mA converter measurement signal. 3. Control module through the relay output, to achieve the set voltage current value of the out-of-range alarm.
8. Transformers ratio setting (full range setting) The full range of current can be set from 5A to 8000A according to the actual installation. The voltage can also be set from 1 to 9999
