Operation

AC Current Measurements
WARNING: To avoid electric shock, disconnect the test leads from the meter before
making current measurements.
1)
Set the Function switch to the 40 or 200A AC range.
2)
Press the jaw trigger and clamp around, fully enclosing a single conductor. Do not
allow a gap between the two halves of the jaw.
3)
Read the ACA value on the LCD.
DC Current Measurements
WARNING: To avoid electric shock, disconnect the test leads from the meter before
making current measurements.
1)
Set the Function switch to the 40 or 200A DC range.
2)
Press the DCA zero key to null the meter display.
3)
Press the Trigger to open the current sense Jaw.
4)
Fully enclose the conductor to be measured. Do not allow a gap between the two
halves of the jaw.
5)
Read the DCA value on the LCD.
AC Voltage Measurements
WARNING: To avoid electric shock or damage to the meter, do not make any voltage
measurements that exceed the maximum specified.
1)
Set the Function switch to the VAC position.
2)
Insert the test leads to the meter as follows: Red lead to "V,Hz,Ω" terminal; Black
lead to the COM input.
3)
With the pointed end of the test leads measure voltage. Remember that voltage
measurements are made in parallel with the device or circuit under test.
4)
Read the ACV value on the LCD.
DC Voltage Measurements
WARNING: To avoid electric shock or damage to the meter, do not make any voltage
measurements that exceed the maximum specified.
1)
Set the Function switch to the VDC position.
2)
Insert the test leads to the meter as follows: Red lead to "V,Hz,Ω" terminal; Black
lead to the COM input.
3)
With the pointed end of the test leads measure voltage. Remember that voltage
measurements are made in parallel with the device or circuit under test.
4)
Read the DCV value on the LCD.
Resistance and Continuity Measurements
WARNING: To avoid electric shock or damage to the meter, remove power to the circuit
under test and discharge all capacitors.
Set the Function switch to the Ω position.
1)
2)
Insert the test leads to the meter as follows: Red lead to "V,Hz,Ω" terminal; Black
lead to the COM input.
3)
With the pointed end of the test leads measure resistance. Remember that
resistance measurements are made in parallel with the device or circuit under test.
4)
Read the resistance value on the LCD.
5)
If the resistance is less than 40Ω, the continuity beeper will sound.
