HOW

MEASURE

CURRENT

[] Plug the black test lead into the jack marked

-COM.

Plug

the red test lead into the jack marked VOA.

_} Set the upper slide switch

to the +DC

position.

Set the

lower slide switch to Mes

(] Set the selector switch to the MA current range you wish to

measure. Always start at the highest range and then reset

the switch to obtain a convenient reading.

CAUTION:

Although the meter incorporates protection for the

movement,

never

connect

the test leads across

any

source

voltage when measuring current, or damage may result.

-] Open the circuit in which the current is to be measured.

Connect the black test lead to the negative side of the cir-

cuit break, and the red test. lead to the positive side.

Apply power to the circuit. The value of the measured cur-

rent can now be read from the appropriate meter scale, tak-

ing into account the setting of the selector switch and scale

multiplier switch.

For readings of 0-80 pa, set the selector switch to .16 and the

scale multiplier switch to ae Read on the 0-80 DC scale,—each

division being equal to 2 pa.

For readings of 0-160 ya, set the selector switch to .16 and the

scale multiplier switch to VA. Read on the 0-16 DC

scale, —

each division being equal to 4 pa.

For readings of 0-400 ya, set the selector switch to .8 and the

scale multiplier switch to ". Read on the 0-400 DC scale, —

each division being equal to 10 pa.

For readings of 800 pa, set the selector switch to .8 and the

scale multiplier switch

to VA. Read

on the 0-80 DC

scale, —

each division being equal to 20 pa.

For readings of 0-8 ma, set the selector switch to 16 and the

scale multiplier switch to Lice Read on the 0-80 DC scale,—each

division being equal to .2 ma.

For readings of 0-16 ma, set the selector switch to 16 and the

scale multiplier switch to VA. Read on the 0-16 DC scale, —

each division being equal to .4 ma.

400MA

For readings of 0-200 ma, set the selector switch to 16A and

the scale multiplier switch to A

. Read on the 0-200 DC scale,—

each division being equal to 5 ma.

400MA

For readings of 0-400 ma, set the selector switch to 16A and the

scale multiplier switch to VA. Read on the 0-400 DC scale, —

each division being equal to 10 ma.

400MA

For readings of 0-8 amps, set the selector switch to 16A and

the scale multiplier switch to va. Place the red test lead into the

jack marked +16A. Read on the 0-80 DC scale. — each division

being equal to 200 ma.

400MA

For readings of 0-16 amps, set the selector switch to 16A and

the scale multiplier switch to VA. Place the red test lead into

the jack marked

+16A. Read

on the 0-16 DC

scale, —

each

division being equal to 400 ma.
