Ⅰ.Features

1.Accurate AC digital clamp meter for leakage current measurement.

2.10μA high resolution on 40mA range.

3.Shield transformer jaws to minimizs the effect of external stray
magnetic field.

4.Large jaw with 30 mm diameter.

5.Five Ranges (40mA, 400mA,4A,40A,100A)for all application.

6.A filter circuit is designed to eliminate the effect of high frequency
noise and harmonics by setting the frequency selector switch at the
50/60 Hz position for AC current measurement.

7.Large 3 3/4 digits LCD

8.Fast bargraph display (20 times/sec.)for transient observation.

9.Continuity and frequency measurements.

10.Max/Min and Data Hold functions.

11.Relative Measurement.

12.600V overload protection for ohm measurement.

13.Easy single rotary switch for any function selection.

Ⅱ.Panel Description

1.Transformer Jaw

This is used to pick up current signal.To measure DC/AC current,

conductor must be enclosed by the jaw.

2.Transformer Trigger

This is used to open the jaw.

3.Function Selector Switch

This is used to select the function user desired, such as ACV ,ACA,ohm

and continuity.

4.Frequency Selection Switch

At 50/60Hz position,only the low frequency signal is measured.At wide

position,signal from 40-1KHZ is measured.

5.Data Hold Button

once this button is pushed,reading shall be held on the LCD. Press

again to release it.

6.Max/Min Hold Button

This button is used to enable the maximum or minimum value to be

displayed and updated during measurement. Press once, minimum
value shall be displayed and updated. press again, maximum value shall
be displayed and updated. Press again (the third push ),clamp meter
return to normal measurement mode.

7.Zero/Relative Button

once this button is pressed, the current reading shall be set to zero and

be used as a zero reference value for all other subsequent
measurement.

8.LCD

This is a 3 3/4 digit liquid crystal display with maximum indication off

3999. Function symbols, units, bargraph, sign, decimal points, low
battery symbols, Max/Min symbols, and zero symbol are included.

9.Low Battery Symbol

When this symbol appears, it means the battery voltage drops below the

minimum required voltage. Refer to Section V for battery replacement.

10.Zero/Relative Symbol

When this symbol appears, it means a reference value has been

subtracted from the actual reading. The reading shown is a offseted
value. Press and hold the zero button for 2 seconds to disable this
function.

11.Data Hold Symbol

Once the hold button is pressed, this symbol appears on LCD.

12.Bargraph

Bargraph has forty segments. It displays segments proportional to the

actual reading. Each segment represent one count.

13. Max/Min Hold symbol

Once the Max/Min button is pressed, either MAX or MIN shall be

displayed on LCD.

14.Continuity Symbol

If ohm and continuity function is selected, this symbol shall appears on

LCD.

15.Units symbols

Once a function is selected, corresponding unit (V,Ω, A，or Hz) shall be

displayed on LCD.

16.V Ω Hz input Terminal

This terminal is used as input for voltage, ohm/continuity, or frequency
measurements.

17.COM Terminal

This terminal is used as common reference input.

18.Hand strap

Put your hand through the hole of hand strap to avoid accidental drop of

the clamp meter.
