Functions

• The YC98S1 has a 480x234 dot color LCD screen. It incorporates a 48 keys keyboard with which is very easy to access to the following main 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).
• CT ratio test: getting CT ratio by synchronously testing primary and secondary current of CT.
• Judge the wire connection right or wrong automatically.
• Meters test: Synchronously test two meter's error or one meter's active and reactive error.
• It has a USB port, the testing data can be storaged in the removed disk that connect on USB prot. Quantity of testing data depend on the removed disk's capacity.
• The storage data include serial number, meter type (active or reactive), constant, type of test (automatic.manual) and number of disks revolutions or pulses of each test, error, date and time... 
• Fireware can be upgraded through removed disk by users themselves.
• It has a RS232 interface to communicate with a PC.
