The YC98S1 is a portable standard to verify active and reactive three phase meters (3 or 4 wires) and single phase meters (2 or 3 wires). It is designed to work in the field or in the laboratory.

Features

    *0.05% High accuracy (direct connection)
    *With 7 inch 480×234 dot TFT color screen
    *Wide voltage supply range: 55V~480V
    *Connection with current clamp: standard 100A. From 5A to 2000A current as option.
    *Two ways for power supply:external AC power supply or test lead power supply


Functions

    *Measuring mode: gives information about the parameters of the line under test, like:
        ·Phase voltage, current, phase angle.
        ·Active power, reactive power, apparent power.
        ·Phase and three-phase power factor..
        ·Phase angle of phase to phase voltage, phase angle of phase to phase current
        ·Frequency.
    *Vector diagram: draws the line vector diagram.
    *Wave form: shows the wave form of current and voltage.
    *Harmonics: makes a graphic and numeric analysis of the THD (2-21 degrees).
    *Meters test: Performs the test to the meters. The data field configurable in this function is the serial number, the meter type, the constant, the divisor factor (for HF), the type of test and cycles.
    *CT ratio test: get CT ratio by synchronously testing primary and secondary current of CT
    *Wiring check: judge the wiring right or wrong automatically
    *Energy accumulating: accumulate active and reactive energy in a setting time, used for meter's dial test
    *Clamp CT self-calibration: check whether the clamp CT is accurate and re-calibration.
    *Test data storage: can store 5000 data groups. Data include meter type, serial number, constant, error, date, etc
    *Download the testing program: can download 5000pcs testing planning to the equipment, convenient for local use
    *It has a RS232 interface to communication with a PC
    *It has a USB port, the testing data can be stored in the removed disk that connect on USB port. Quality of testing data depend on the removed disk’s capacity
    *Firmware can be upgraded through removed disk by users themselves
    *Can be connected with external printer, keyboard, barcode scanner
