Connect CoM input to neutral or ground terminal.
Connect ‘ + ‘ input to Ø 1 terminal
Clamp jaws around to Ø 1 wire
The display will show reading, W (real power), VA (apparent power)or VAR (reactive
power) measurement and Pf.
write down the reading as kw1, kVA1, kVAR1
Connect CoM input to neutral or ground terminal.
Connect ‘ + ‘ input to Ø 2 terminal
Clamp jaws around to Ø 2 wire
The display will show reading, W (real power), VA (apparent power) or VAR (reactive
power) measurement and Pf.
write down the reading as kw2, kVA2, kVAR2
Connect CoM input to neutral or ground terminal.
Connect ‘ + ‘ input to Ø 3 terminal
Clamp jaws around to Ø 3 wire
The display will show reading, W (real power), VAR (reactive power) or VA (apparent
power) measurement and Pf.
write down the reading as kw3, kVA3, kVAR3

kw Total 3 * kw1 kw1 + kw2 + kw3
kVA Total 3 * kVA1 kVA1 + kVA2 + kVA3
kVAR Total 3 * kVAR1 kVAR1 + kVAR2 + kVAR3
Power factor (Pf)
Total Power factor = Real Power (V rms * A rms * Cos θ )/Apparent Power (V rms * A rms)
“A-lags” annunciator indicates an inductive circuit, or Current A lags Voltage V (phase-
shift angle θ is “+”).
“A-lags” not visible indicates a capacitive circuit, or Current A leads Voltage V (phase-shift
angle θ is “-”).
MAINtENANCE AND REPAIR
if there appears to be a malfunction during the operation of the meter, the following
steps should be performed in order to isolate the cause of the problem:
Check the battery.
Review the operating instructions for possible mistakes in operating procedure.
inspect and test the test leads for a broken or intermittent connection.
except for the replacement of the battery or test probes, repair of the multimeter
should be performed only by a factory Authorized Service Center or by other qualified
instrument service personnel. The front panel and case can be cleaned with a mild solution
of detergent and water. Apply sparingly with a soft cloth and allow to dry completely
before using. Do not use aromatic hydrocarbons or chlorinated solvents for cleaning.
