AC Current Measurement

Set the function/range selector to the appropriate A B

position (400 or 600 A).

Open spring-loaded clamp by pressing the lever on left

side of meter.

Position clamp around one wire or conductor and release

the clamp lever. Make sure that the clamp is entirely

closed. The clamp must be positioned around only one

conductor. If it is placed around two or more current

carrying conductors, the reading is FALSE.

Read the displayed value.

DC and AC Voltage Measurement

The maximum input voltage for DC or AC Volts is 600 Vrms. Do

not attempt to take any voltage measurement that exceeds

600 Vrms to avoid electrical shock hazard or damage to the

instrument.

Set the function/range selector to the appropriate V F

(600 V) or V B (400 or 600 V) position.

Connect the black test lead to the "COM" terminal and the

red test lead to the "VΩ'' terminal. Connect probe tips to

the circuit and read the value.

Note: Both ammeter and voltmeter can be used for frequency

measurement. The clamp-on Ammeter detects the frequency of

the current circulating in the cable or bus-bar under test (the

current must be greater than 1 A in the 400 A range and greater

than 15 A in the 600 A range). The Voltmeter detects the

frequency of the voltage applied to the leads.

In either set-up (current or voltage measurement), set the

function/range switch to the Hz position.

Read the frequency value on the display.
