UT501B Insulation Resistance Tester is designed with brand-new

design and combination of massive integrated and digital circuits; it

can measure insulation resistance, low resistance, AC voltage, etc,

and enjoys high degree of accuracy, stable performance, easy

operation and reliability. It is used for insulation resistance

measurement for insulation materials and various kinds of electric

equipments such as transformer, electric machines, cables,

switches, electrical appliances, a ideal tool for electric equipment

maintenance, testing and inspection.

Safety Information

Warning

The tester is designed and manufactured in compliance with

IEC61010 standard. The manual covers safety information related

to the safe operations and conditions of the instrument. please read

carefully before using the instrument.

Use always as specified in the manual, and keep it for future use.

6. Rotary knob set to 250V/500V/1000V:

to select test voltage for insulation resistance measurement.

If low battery indicator shows on upper left corner of LCD after the

meter is turned on, it means battery is almost used up and need to

be replaced.

(2) Insert the red test lead into "V" jack and the black test lead

into "G" jack.

Please take extreme caution in order to avoid electric shock when

measuring high voltage.

Disconnect test leads and tested circuits and remove test leads

away from input jacks after completing the measurement.

With the knob already set to test voltage 250V/500V/1000V, then

press TEST button,the instrument will be self-locked to measure

continuously. The test voltage will be output and TEST button will

light up. With the measurement finished, press TEST button to

unlock and stop the measurement.

When red and black clips are connected to the circuit under test,

high voltage is output from LINE jack and the current from

EARTH jack.

Under insulation measurement mode, press PI/DAR button once

to select PI parameter, the screen displays Time 1(1min)/Time2

(10mins), then press TEST to start PI measurement.

Cleaning the housing

Clean the instrument surface with soft cloth or sponge

dampened with clean water.

To avoid damage to the instrument, do not submerge it into

the water.

When it is necessary to verify or repair instrument, please

deliver the instrument to qualified professional serviceman

or designated repairing department.
