5. Preparation
5-1 Checking Battery Voltage
Set the Function Selector Switch to other positions except the OFF position.
Battery Voltage is enough if indication is clear and
symbol is not indicated in this bout.
If symbol is indicated or no indication on the display, follow to the Battery
Replacement procedures shown in item8 in this document and replace with new batteries.
6. Measurements
6-1 Voltage Measurement (DCV, ACV)
DANGER
● 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 Function Selector Switch during measurement.
● Do not make measurement when opening the battery cover and the instrument case.
6-1-1 DC Voltage Measurement (DCV)
(1) Insert the black test lead plug into the COM terminal and the red test lead plug into the VΩHz terminal.
(2) Set the Function Selector Switch to " " position.(Then, "AUTO" and "mV" symbols are indicated on the display.)
(3) 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, then the measured value
is indicated on the display. If you connect the test leads the other way, "ー" symbol is indicated on the display.
6-1-2 AC Voltage Measurement (ACV)
(1) Insert the black test lead plug into the COM terminal and the red test lead plug into the VΩHz terminal.
(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 20mV at the AC400mV range, the measurement value cannot be indicated correctly.
Even if short-circuit the input line at the range of AC4V, 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 300V AC/DC. (electrical potential to ground 300V AC/DC)
● Do not operate 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 400mA)
(1) Insert the black test lead plug into the COM terminal and the red test lead plug into the mA terminal.
