(2) Set the Function Selector Switch to "

" position.(Then, "AC", "Auto", and "V" symbols are indicated on the display.)

(3) Connect the test leads to the circuit under test.

Measured value is indicated on the display.

Note)  When you make measurement of the voltage less than 0.1V at the AC6V range, the measurement value cannot be indicated correctly.

Even if short-circuit the input line at the range of AC6V, 1〜3dgt may remain indicated.

In that case, by pressing "REL" Key, "0" will be indicated.

6-2  Current Measurement (DCA/ACA)

DANGER

● Do not apply voltage to the current measuring terminals.

● To avoid the danger of getting electrical shock, never make measurement on a circuit over 600V AC/DC. (electrical potential to ground 300V AC/DC)

● Do not operate the Function Selector Switch during measurement.

● Do not make measurement when opening the battery cover and the instrument case.

6-2-1  DC Current Measurement (up to 600mA)

(1) Insert the black test lead plug into the COM terminal and the red test lead plug into the mA terminal.

(2) Set the Function Selector Switch to the appropriate "uA" or "mA" position.

In  case  that  the  measurement  current  is  6000uA  or  less,  set  the  Function  Selector  Switch  to  "uA"  position,  and  it  is  600.0mA  or  less,  set  the  Function

Selector Switch to "mA" position.(Then, "DC" , "Auto", and "uA"or "mA" symbols are indicated on the display.)

(3) Power off the circuit under test.

(4) Connect the black test lead to the negative side of the circuit under the test and the red test lead to the positive side of the circuit so the instrument is in the

series with the circuit.

(5) Power on the circuit under test.

(6) Measured value is indicated on the display.

If you connect the test leads the other polarity, "ー" symbol is indicated on the display.

6-2-2  DC Current Measurement (up to 10A)

CAUTION

● For safety sake, the measuring time on 10A range should be 15 seconds or less. Interval time between 2 measurements should be greater than 15 minutes.

If  you  carry  on  making  measurement  continuously  over  15  seconds,  or  make  measurement  in  short  interval  time,  it  may  cause  error  of  measurement  and

instrument damage.

(1) Insert the black test lead plug into COM terminal and the red test lead plug into the 10A terminal.

(2) Set the Function Selector Switch to the "A" position.(Then, "DC" , "Auto", and "A" symbols are indicated on the display.)

(3) Power off the circuit under test.

(4) Connect the black test lead to the negative side of the circuit under the test and the red test lead to the positive side of the circuit so the instrument is in the

series with the circuit.

(5) Power on the circuit under test.

(6) Measured value is indicated on the display.

If you connect the test leads the other polarity, "ー" symbol is indicated on the display.

6-2-3  AC Current Measurement (up to 600mA)

(1) Insert the black test lead plug into the COM terminal the red test lead plug into the mA terminal.

(2) Set the Function Selector Switch to the appropriate "uA" or "mA" position.

In the case of the measurement current is 6000uA or less, set the Function Selector Switch to "uA" position, and it is 600.0mA or less, set the Function

Selector Switch to "mA" position.(Then, "DC" , "Auto", and "uA"(or "mA") symbols are indicated on the display.)

(3) Set the instrument to AC mode by pressing "SELECT" Key.(Then, "AC" symbol is indicated on the display.)

(4) Power off the circuit under test.
