measurement, the display value as the input value minus

the difference between the reference value.

so REL△(current reading) = input value - reference value

3) The relative value of the measurement can be carried

out in a certain range that is to say under the measurement

mode to have this feature.

notice：

Measuring instrument in the Maximum / minimum state, it

cannot switch to the frequency, duty ratio measuring mode.

measurement.

4.3 The maximum value and minimum value measurement

1）Press“MAX MIN”enter the manual range mode，display Max

Value；Then press this button to display the "Min" value；

press again and display “Max-Peak Min"；Repeat this

cycle. Press the "MAX MIN" button for more than 2 seconds

to exit this mode.

2）In Max mode, automatically saved the maximum value of

the measurement.

3）In Min mode, automatically saved the minimum value

measurement.

4）Enter the Max Min mode, automatically save the measured

difference

5）Press the "MAX MIN" button for more than 2 seconds to

exit this mode, the instrument is restored to normal

state measurement.

4.4 function exchange

1） In resistance state，press“SEL”button，In the

resistance, capacitance, diode on-off detecting,

77

four gear cycle switch.

2） In the voltage profile, click "SEL", switch between DC

and AC

3） In the temperature profile, click "SEL", switch between

in Celsius and Fahrenheit .

4.5 RAN measurement

1）RANE keys for automatic/manual switch range trigger this

action, boot or turn the dial, the default for the

automatic range. Click on the switch for manual range. IN

manual mode, the range per click this button to jump up

one notch, to the Max value and then click this button will

jump to the mix value in turn .Frequency and capacitance

measurement without manual range. Such as press RANGE for

more than 2 seconds or rotary switch, the exit RANGE

manually.

4.6 Backlight and lighting clamp head

1）In the process of measurement, if the ambient light is

too dark, difficulties to get resulting,press the

“ ”key more than 2seconds，Otest lead the back

light, automatically shut down in about 30 seconds.

2）If press“ ” key more than 2seconds and willturn

off the power.

3) In the current file,when otest lead the instrument

backlight will also otest lead the clamp head too,The

luminous body is LED，working current is large, while

the meter is provided with a timing circuit (timing

is about 30 seconds), but often use the backlight will

shorten the battery life, so unnecessary should

minimize the use of back light.

notice：

When the battery voltage≤3.9V，display“ ”（Undervoltage）

Symbol。Use the backlight，When the battery voltage≥3.9V，

78

Because the large working current, the battery voltage drop,

“ ”symbol may be displayed（“ ”symbol is displayed,

does not guarantee the accuracy of measurement），it cannot

replace the battery， use until without backlight conditions

in Normal “ ”Symbols show to replace.

4.7 Automatic shutdown

1）Without operation after 15 minutes ，The meter will enter

the sleep state automatically shut down to save power.

1 minutes before the shutdown, the buzzer 5 sound prompt,

dormant into a long sound after that before the shutdown.

2）After the automatic shutdown, press the SEL button, reset

instrument

3）If the boot and press "SEL" button in the same time,

it will cancel the automatic shutdown function.

4.8 Buzzer

Press any key or switch the rotation function, if the

function key is effective, the buzzer will be issued "Beep"

sound (about 0.25 seconds);set in measuring voltage or

current is greater than the alarm value，For example, AC

voltage greater than 600V DC voltage is greater than 600V,

AC / DC current is more than 600A, the buzzer will continue

as pronunciation and to be a overrange alarm; 自

Automatically shut down about 1 minutes before the buzzer

will sound a warning for the issue of 5 times, before the

shutdown will send a warning buzzer sound; ； Automatic

shutdown function is cancelled; every 15 minutes take 5

warnings.

4.9 Measurement

1）Toggle the switch and open power, If the battery and

voltage

79

Is not enough（about≤3.9V

The LCD display“ ”symbol then the battery should be

replaced

2） “ ”symbol，The input voltage or current should not

exceed the value indicated, this is to protect the

internal circuit from being damaged.

3）Switch measuring function and range in the required

4）Connect the public test line, and then connected test

line is When in wiring, The test should be removed first

line charged dismantling wiring.

4.10 Current measurement

Warning

An electric shock hazard.

In current clamp measurements before the test probe is

removed from the instrument.

1）Switch in the A position measuring range. At this time

for the measurement of AC current state, select the

appropriate range

2）Hold the trigger and otest lead the clamp，A wire line

is measured clip in the meter.

3）Read the current value in the LCD display

notice：

1）It cannot get the correct measurement results if use more

than two or much more wire way in the same time.

2）In order to obtain accurate readings，The measured wire

under the current clamp center as much as possible

3）“ ”show the Maximum input AC current is 600 A
