2. Step by Step Procedures:

a. MEASURING DC VOLTS

CAUTION!

Do not attempt to make a voltage measurement

if a test lead is plugged in the A or µmA input

jack. Instrument damage and/or personal

injury may result.

ARNING!

Do not attempt to make a voltage measurement

of more than 1000V or of a voltage level that is

unknown.

Instrument set-up:

FUNCTION BLACK RED MINIMUM MAXIMUM

TEST LEAD TEST LEAD READING READING

mV COM VΩ 0.1mV 400.0mV

V COM VΩ 0.001V 600V

Measurement Procedure:

1. Disconnect power to the circuit to be measured.

2. Plug the black test lead into the COM input jack.

3 Plug red test lead into the VΩ input jack.

4. Set rotary switch to either the mV or V range,

depending on the voltage to be measured.

5. Connect the test leads to the circuit to be measured.

6. Reconnect power to the circuit to be measured.

7. Read the voltage on the 126.

Application Notes

When measuring DC Voltage of a bat-

tery, the most accurate reading can be

attained by testing the battery under

load. To accomplish this, follow steps 1

through 4 shown on page 10 and the

following:

• Connect the red test lead from the

meter to the positive (+) terminal of

the battery.

• Connect the black test lead to the

negative (-) terminal of the battery.

• Reconnect power to the circuit and

read the voltage on the 126.
