6. Data Transmission to PC
The accessory USB-RS232 connection line is used for communication of
the meter with PC. With the meter powered on and the software running,
several following operations such as history lookup, data recall, save,
report sheet, history printing can all be performed. The more data the meter
saves, more time it will take to read out. History data can be saved in Txt
or Excel format.
7. Measurement
Electric Shock, Danger! To avoid any damage to the meter or
personal injury in case of electric shock, only trained and authorized
staff is allowed to operate and should strictly observe safety rules
Danger! To avoid any damage to the meter or personal injury in
case of electric shock do not measure circuit voltage above 600V
Danger! Do not measure current above 20A, otherwise it may
damage the meter!
Connect wires as specified in the manual and avoid wrong inserts
between I1 and I2 .
Disconnect test leads with conductors before unplugging out of the
meter after measuring.
Measuring phase relations for the meter: U1U2, I1I2, U1I1,U2I2, the
former signal always precedes the latter
P1, Q1, S1, PF1 are parameters of U1-I1 and P2, Q2, S2, PF2 for
U2-I2 parameters
Voltage terminals U1, U2 are named the same with red marks on
current clamps.
Current clamping direction should accord with those red marks on
the clamp during phase measuring.
