WARNING!

1. DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE
RATINGS:

- Voltage is not to exceed 800 Volts.

- Wattage, Resistance and Continuity functions are not to
be performed on circuits capable of delivering greater than
600 Volts.

- Current measurements are not to be performed on cir­cuits capable of delivering greater than 500 Volts

2. To avoid electrical shock hazards and/or damage to the
meter:

- Do not exceed the voltage ratings for the meter. Use
caution when measuring voltage.

- Do not use during electrical storms. AC power sources
with inductive loads or electrical storms may result in high
voltage. High energy transients can damage meter and pre­sent a dangerous shock hazard.

- Turn off power to the circuit or device being measured
before taking resistance and capacitance measurements.
Fully discharge all capacitors before measuring.

3. Ensure meter is in proper working order before using.
Visually inspect meter for damage. Performing a continuity
check can verify proper operation. If the meter reading goes
from overload to zero, this typically means the meter is in
proper working order.

4. Visually inspect leads for damage before using. Replace if
insulation is damaged or leads appear suspect.

5. Never ground yourself when taking electrical measurements.
Do not touch exposed metal pipes, outlets, fixtures etc.
Keep your body isolated from ground by using dry clothing,
rubber shoes, mats, or any other approved insulating mater­ial. Keep your fingers behind the finger guards on the
probes. Work with others.

6. Before beginning all unknown measurements, set meter to
highest possible range.

7. Before breaking a circuit for testing, turn off the power to the
circuit. When disconnecting from a circuit, disconnect the
hot lead first, then the common lead.

8. Disconnect the meter from the circuit before turning off any
indicator, including motors, transformers, and solenoids.

Data Hold Button

• The data hold button is used to capture and hold a reading
on the LCD display.

• Press the button again to release the reading.

LCD Display

• 3-3/4 digit display with maximum indication of 3999.

• Function symbols, units, analog bargraph, low battery sym-

bol, min/max symbols, relative symbol, and zero symbol are
included.

Function Buttons
DC A/W ZERO Button

• The DC A/W Zero button is used to zero out the DCA resid­ual value.

• Press this button until the LCD displays a zero value and
the zero symbol.

• This button does not force the meter into manual range
mode.

• Press and hold the DC A/W Zero button for 2 seconds to
disable this function.

REC Button

• The meter can store 4 data points in memory.

• Pressing the REC button will store the current value into

memory.

• The data point number (1-4) will be shown on the upper
display, and the stored data will be shown on the main dis­play for approximately 3 seconds.

• After all four data points have been stored, the meter will
display FULL on the secondary display when the REC but­ton is pressed.

• When data is stored in memory, the REC symbol is shown
on the LCD display.

• This data can be viewed by pressing the READ NEXTbutton.

• This data is stored until the meter is turned off.

3φKVAR KVA Button

• The 3φKVAR KVA button toggles between the KVAR/KVA
measurements and the PF/kW measurements in the 3φ3W
or 3φ4W functions.

• Toggling between these measurements can only be done
after the power clamp has calculated the power factor and
kW measurement.

Read Next Button

In 3φ3W Function

• Pressing the read next button stores the measured values
for kW

RS(L1L2)

/kVA

RS(L1L2)

and moves to the next measurement.

• Pressing read next after the kW

TS(L2L3)

/kVAR

TS(L2L3)

stores the
values and calculates the kW and PF values for the 3φ3W
system.

• After these values have been calculated, press the 3φKVAR
KVA button to display the KVAR and KVA values for the sys­tem.

• To start another calculation, press the read next button again
to return and take a measurement for the kW

RS(L1L2)

/kVARS

(L1L2)

values.

In 3φ4W Function

• Pressing the read next button stores the measured values
for W

R(L1)

/PF

R(L1)

and moves to the next measurement.

• Pressing read next after the W

S(L2)

/PF

S(L2)

stores the values

and moves on to the next measurement.

• Pressing read next after the W

T(L3)

/PF

T(L3)

stores the values

and calculates the kW and PF values for the 3φ4W system.

• After these values have been calculated, press the 3φKVAR
KVA button to display the KVAR and KVA values for the sys­tem.

• To start another calculation, press the read next button again
to return and take a measurement for the W

R(L1)

/PF

R(L1)

values.

6

In any other function

• Pressing the read next button in any other function displays
the measurement values stored with the REC button.

• The REC NO. symbol will be shown on the LCD display and
the record number will flash on the secondary display to noti­fy the user of what values are being displayed.

• Pressing this button after the meter displays last stored data
point returns to the first stored data point.

• To exit the read next mode, turn the function switch to any
other function. This will exit without losing the stored data.

To measure Kilowatts and Power Factor in a single
phase 2-wire system

• Set rotary switch to PF/kW without jaws clamping onto any
wire

• If the watt reading is not zero, press the DC A/W ZERO
button once to zero out the watt reading.

• Insert the black test lead into the COM terminal and the red
test lead into the + terminal.

• Connect the black test probe to the neutral conductor and
the red test probe to the hot conductor.

• Using the trigger to open the jaws, fully enclose the hot
conductor within the clamp.

• Release the trigger and be sure that the jaws have closed
completely.

• The power clamp selects the appropriate range based on the
Autoranging table.

• Power Factor (PF) is a calculated value based on the
formula

PF=_______

• The kW value is shown on the main display and the PF
value is shown on the upper display.

• Positive PF (+) indicates an inductive load, while negative
PF (-) indicates a capacitive load.
