OPERATION

Before taking any measurements, read the Safety Information Section.

Always examine the instrument for damage, contamination (excessive dirt,

grease, etc.) and defects. Examine the test leads for cracked or frayed

insulation. If any abnormal conditions exist do not attempt to make any

measurements.

HButton

Involtage,current,frequencyanddoidefunctions,Press" H "buttontotoggle

in and out of the Auto Hold mode, the " H" annunicator is displayed. In Auto

hold mode, the meter will capture and hold the first stable non-zero(>100

digits) reading after a zero reading(<100 digits). Several consecutive mea-

surements can be held and displayed without pressing the (A-H) buttion.

Simply by shorting the test leads together between measurements. In resis-

tance,continuityandtemperaturefunctions,press" H "buttontotoggleinand

out of the Data Hold mode, the " H" annunicator is displayed.

PEAK HOLD Button: (only AC functions 40-60Hz)

Press "PEAK" button to toggle in and out of PEAK Hold mode. In the PEAK

Hold mode, the "MAX P " annunciator is displayed. [Accuracy: ±(10% rdg +

10dgts), effect reading: 800~4300]

MIN / MAX button

Press(MAX/MIN)toentertheMAXMINAVGRecordingmode(manualrange

only).TheRECORDannunciatorturnsonandtheautomaticpower-off feature

is disabled.

Push (MAX/MIN) to cycle through the maximum(MAX), minimum(MIN),

average(AVG)andpresentreadings.(AVG)isaveragelasttentimesreading

can be displayed. Press and hold down the (MAX/MIN) for 2 seconds to exit

and erase recorded reading.

DZERO Button

In voltage, current, frequency and doide functions, Press (DD

DZERO) button to

toggle in and out of the Relative mode, the "ZERO" annunciator turn on, zero

the display, and store the displayed reading as a reference value.

RANGE Button

Press (RANGE) button to select the Manual Range mode and turn on the "

" annunciator. (The meter selected next range it was in when manual ranging

was selected).

In the Manual Range mode. each time you press (RANGE) button, the range

(and the input range annunciator) increments, and a new value is displayed.

To exit the Manual Range mode and return to autoranging, press and hold

down (RANGE) button for 2 seconds. The " " annunciator will disappear.

Voltage Measurements

1.Connecttheredtestleadtothe"V"jackandtheblacktestleadtothe"COM"

jack.

2.SettheFunction/Rangeswitchtothedesiredvoltagerange(ACorDC). The

meter will automatically select the best voltage range.

3. Connect the test leads to the device or circuit being measured.

4.Fordc,a(-)signisdisplayedfornegativepolarity;positivepolarityisimplied.

Current Measurements

1. Set the Function/Range switch to the desired highest 700A range (AC or

DC). In DC current measurement use DD

DZERO button, offset the residual

magnetic of the jaws.

2. Press the trigger to open transformer jaws and clamp onto one conductor

only. Read the current directly on the display. It is recommended that the

conductorbeplacedatthecenteroftheclosedjawsformaximumaccuracy.

3.Whenthereadingislowerthan 430counts,settherangeswitchto thenext

lower range position. For maximum accuracy, select the lower range

possible without overranging the meter.

Resistance Measurements

1. Set the Function/Range switch to the resistance range.

2. Remove power from the equipment under test.

3.Connecttheredtestleadtothe"+"jackandtheblacktestleadtothe"COM"

jack.

4. Touch the probes to the test points. In ohms, the value indicated in the

display is the measured value of resistance.
