ROLLS DIGITAL MULTIMETER

MU118 OPERATION MANUAL

1. INTRODUCTION

This instrument is compact, rugged, battery operated, handheld 3

1/2 digit digital multimeter for measuring DC and AC voltage, DC

and AC current, resistance and diode, capacitance, transistor,

continuity test, temperature and frequency.

The dual–slope A-D converter uses C-MOS technology for

auto-zeroing, polarity selection and over-range indication. Full

overload protection is provided. It is an ideal instrument for use in

the field, laboratory, workshop, hobby and home applications.

2. FEATURES

* Push-button ON-OFF power switch.

* Single 30 position easy to use rotary switch for function and range

selection.

* High sensitivity of 100µV.

* Automatic over range indication with the “1” displayed.

* Automatic polarity indication on DC range.

* All ranges fully protected.

* Resistance measurements 0.1Ω to 200MΩ.

* Capacitance measurements 1pF to 20µF.

* Diode testing with 1mA fixed current.

* Transistor hFE test with Ib≈100µA.

* Temperature measurement with or without K type thermocouple.

5. OPERATION

1. Check the 9-volt battery by setting the ON-OFF switch to ON. If the

battery is weak, a sign will appear on the display. It is does not

appear on the display, proceed as below. See maintenance if the

battery has to be replaced.

2. The mark or sign next to the test lead jacks is for warning that

the input voltage or current should not exceed the indicated

values. This is to prevent damage to the internal circuit.

3. The function switch should be set to the range which you want to

test before operation.

4. If the voltage or current range is not known beforehand set the

function switch to a high range and work down.

5. When only the figure “1” is displayed, over-range is being indicated

and the function switch must be set to a higher range.

5.1) DC Voltage Measurement

1, Connect the BLACK test lead to the COM jack and the RED test

lead to the V/Ω jack.

2. Set the FUNCTION switch to the “V range to be used and

connect the test leads across the source or load under

measurement. The polarity of the RED lead connection will be

indicated at the same time as the voltage.

”

NOTE:

Do not apply more than 1000V to the input, Indication is

possible at higher voltages but there is danger of damaging the
