A or W reading (Users do not need to press and hold the button). When the power clamp is doing the zero action, a symbol of ZERO will be shown in LCD. 4500 : 28-09-2012... -
Page 3: Operating Instructions
LCD will show 0 Hz. If the frequency is > 400 Hz, LCD will show 3.2.2. V + A Dual Display Follow Ihe instruction in section 3.6.3 3f AC+DC Balanced Power Measurement V + A. Then users can monitor V and A at the same time from LCD. Fig.3 4500 : 28-09-2012... -
Page 4: Ac+Dc Current Measurement
CAPACITIVE LOAD: Positive phase angle means current signal leads ahead voltage signal. If connection is correct, positive phase Fig.5 angle also means capacitive load. NOTE: The “+” sign printed on jaw must face the power source for correct result. 4500 : 28-09-2012... -
Page 5: A Dual Display
The “+” sign printed on jaw must face the power source for accurate measurement. NOTE : To find out it load is capacitive or inductive, refer to section 3.5 Phase Angle Measurement for details. 3.7. 3f f f f f 3W (No neutral) AC+DC Unblanced Power Measurment. Fig.8 4500 : 28-09-2012... - Page 6 NOTE : In the 3f3W unbalanced power measurement, one of or W could be negative. So users must make sure all the connections and clamping are correct to obtain correct power. 4500 : 28-09-2012...
- Page 7 If the watt reading is not zero, press the DCA/DCW ZERO button once to zero the watt reading e. Camp on to phase where test prod is connected (eg. S or L2 phase) The power clamp will automatically select proper range. 4500 : 28-09-2012...

Page 8: 3F4W Ac+Dc Unbalanced Power Measurement
W must be positive. If users find one negative power, check the connection of test leads and clamping of jaw. Make sure all the connections and clamping are correct to obtain correct Fig.14 power. Fig.16 Fig.15 4500 : 28-09-2012... -
