4. Connect test alligator clips into circuit under test.

5. Push the "Test Button"(3-4, Fig. 1) for measurement.

5-4 Power Lock/Manual(off) Switch

Typically, when make the general measurement, always slide

the "Power Lock/Manual(off) Switch"(3-3, Fig. 1) to the

MANUAL(off) position. Then push the "Test Button" will

power on the meter until release the "Test Button"(3-4,

Fig. 1). However if user intend to power on the meter

permanently & making the measurement continuously, then

it should to slide the "Power Lock/Manual(off)

Switch"(3-3, Fig. 1) to the POWER LOCK position.

Attention :

When the measurement the impedance

( resistance ) value less than 1 Mega-

ohm, the period time of " Power Lock

ON " ( power ON permanently ) should

less than 5 minutes, otherwise the

internal circuit may will be overheated.

6. MEASURING CONSIDERATION

FOR Mega OHM TESTING

1. The amount of time during which the test voltage applied

will also affect the reading. With good insulation, the

measured value of insulation resistance will slowly

increase is applied typically. This is due to dielectric

absorption effect of the applied DC voltage on the bulk

insulation resistance.
