LTR MTI 801 User manual

WARNING

Do not expose the meter to rain or moisture in order to reduce the risk of

fire or electric shock.

Observe the proper safety precautions when working with voltages above

30 V ac rms, 42 V ac peak, or 60 V dc. These voltage levels pose a potential

shockhazardtotheuser.

Inspect test leads, connectors and probes for damaged insulation or exposed

metal before using the meter.

Check the test leads for continuity before use. Do not use if the readings

are high or noisy.

Keep your fingers behind the finger guards of the test leads during

measurement.

Disconnect the test leads from the points before changing functions.

Disconnect circuit power and discharge all high voltage capacitors before

testing resistance.

Always use the proper terminals, switch position, and range for measurements

before connecting the meter to circuit under test.

When servicing the meter, use only specified replacement parts.

Remove test leads from the meter before you open the battery cover.

Donotoperatethemeterwiththebattery cover removed orloosened.

Toavoidfalsereadings,whichcouldresultinpossibleelectricshockorpersonal

injury, replace the battery as soon as the low battery indicator appears.

Avoid working alone.

CAUTION

Disconnect the test leads from the points before changing functions.

Disconnect circuit power and discharge all high voltage capacitors before

testing resistance, or continuity.

Always set the meter to the highest range and work downward for an

unknown value in the manual ranging mode.

Safety Information

MTI 801 Insulation Resistance Tester is a handheld and battery operated,

Average RMS insulation multimeter capable of testing Insulation, AC or DC

Voltages, Resistance and Continuity.

This manual contains information and warnings that must be followed for

operating the meter safely and maintaining the meter in a safe operating

condition. If the meter is not used in a manner specified in this manual, the

protection provid ed by the meter may be impaired.

This meter complies with UL 61010-1 : 3

Edition, CAN / CSA - C22.2

No. 61010-1-12: 3

Edition, IEC /EN 61010-1: 2010; Overload protection

CAT IV 600V and CAT III1000V.

TERMS IN THIS MANUAL

to the user. A

Caution

identifies conditions and actions that could cause

damage the meter or the equipment under test.

SAFETY INFORMATION

OPERATING INSTRUCTIONS

(041710_1)

LOCK

TEST

If the resistance of the device is below 40 Ω, there

is a continuity beep tone.

If the resistance of the device is more than 40 Ω,

there is no beep tone.

This is useful for checking wiring connections and

operation of switches.

CAUTION

Turn off power and discharge all capacitors on

circuit to be tested before attempting incircuit

resistance measurements.

Accurate measurement is not possible if

external or residual voltage is present.

INSULATION TEST

CAUTION

Turn off power and discharge all capacitors on circuit to be

tested before attempting Insulation test.

Insert test leads into V and COM input terminals.

Set the rotary selector to the desired test voltage position.

Connect the lead probes tothe circuit undertest.

The display shows until you press and a valid

insulation resistance reading is obtained.

Press and hold TEST button to start the test.

The LCD shows (high voltage warning) symbol along with

the resistance in MΩor GΩ.

The symbol will be displayed on the LCD until the

TEST button is released. The meter displays symbol along

with the maximum resistance for the range when the resistance

is higher than the maximum display range.

NOTE : When the button is pressed before the TEST

button, the test remains active until the

button is pressed again.

LOCK

Release the button before disconnecting the probes

from the circuit under test. Then, the circuit will automatically be

discharged through the meter.
