Introduction

Congratulations on your purchase of the Extech 380560 (117V) or 380562 (220V) High Resolution

MilliOhm Meter. This device offers seven resistance ranges with resolution as low as 0.01mΩ.

The 4 wire Kelvin clip connection ensures optimum accuracy. The built- -in comparator feature

offers HI GO testing. Typical applications include transformer, motor coil, and PC Board -LO-

resistance measurements. Careful use of this meter will provide years of reliable service.

Meter Description

1. LED Display

2. HI/LO/GO Status Indicators

3. Power and Range pushbuttons

4. Kelvin clip leads

5. SET/TEST and HI/LO pushbuttons

6. Comparator adjustment screws

7. Kelvin clip lead input terminals

Note: The power cable input and audible alert button of the instrument.are on rearthe

Measurement Precautions

Ensure that the meter is connected to the correct power source

(110 model 380560 220V 380562V for or for model ) .

Do not apply voltage to the meter input terminals. Meter damage may result.

Measurement Procedure

1. Connect the Kelvin test leads to the meter.

2. Press the POWER pushbutton to turn power on.

3. the position. Position the SET/TEST pushbutton to TEST

4. To check the meter zero, clip the test leads

together as shown at right.

5. Selec t the desired measuring range using the

labeled black pushbuttons. When the resistance of

the device is unknown, start with the highest range

and work downward.

6. Clip the leads onto the device under test as shown below.

7. Observe the reading . on the LED display

Comparator - - ) Operation (HI LO GO

The meter is equipped with a Comparator function

allowing the user to sort resistance measurements against

programmable HIGH and LOW limits. To program the

comparator:

1. Position the SET/TEST pushbutton to SET.

2. Position the pushbutton to LO/HI LO.

3. e Adjust th LO comparator screw to the desired low

limit . (shown on the LED display)

4. Position the pushbutton to LO/HI HI.

5. he Adjust t HI comparator screw to the desired high limit.

6. Position e pushbutton to th SET/TEST TEST.

7. Set the rear buzzer switch ON or OFF. When ON, the meter will sound an audible tone for each

GO measurement.

Each time a measurement is taken, the appropriate Comparator status LED will light. If the

measurement is lower than the LO setting, the LO LED will light. If the measurement is higher than

the HI setting, the HI . If the reading is between the HI and LO settings, the green GO LED will light

LED will light. If the rear beeper pushbutton is set ON, an audible tone will sound each time a GO

reading is detected.

Measurement Principles

The DC test current flows from the terminal to the through the resistance FORCE+ (F+) FORCE- -(F

) terminal. The S+ and S- (SENSE) terminals measure the DC voltage drop across the device under

test only, thus eliminating the lead and contact resistances. The meter displays the resistance

based on the test current and the measured voltage; refer to the equation below:

Rx = Vx / Is

Where:

Vx is the voltage drop across the device under test;

Is is the test current;

Rx is the resistance of the device under test.
