SECTION 1 –SAFETY INFORMATION

Safety Information

Understand and follow operating instructions carefully.

Use the meter only as specied in this manual; otherwise, the protection provided by the

meter may be impaired.

WARNING

Identies hazardous conditions and actions that could cause BODILY HARM or DEATH

CAUTION

Identies conditions and actions that could DAMAGE the meter or equipment under test

WARNING

- Examine the instrument and probes before use. Do not use the instrument if it is

wet or damaged

- When using test leads or probes, keep your ngers behind the nger guards.

- Remove the test lead from the instrument before opening the battery cover or

instrument case.

- Always use the correct terminals, switch position and range for measurements.

- Never attempt a voltage measurement with the test leads inserted into the“A”

input terminals.

- Verify the instrument is operating correctly by measuring a known voltage before

use. If in doubt, have the instrument serviced.

- Do not apply more than the rated voltage, as marked on the instrument, between

terminals or between any terminal and earth ground.

- Do not attempt a current measurement when the open-circuit voltage is above

the fuse protection rating.

- Only replace a fuse with the correct type and rating as specied in this instruction

manual.

- Use caution when measuring voltages above 30 Vac rms or 60 Vdc. These

voltages pose a shock hazard.

- To avoid incorrect readings that can lead to electric shock, replace the battery as

soon as the low battery indicator appears in the display.

- Disconnect the circuit power and discharge all high-voltage capacitors before

making resistance, current, continuity, diode or capacitance measurements.

- Do not use the instrument in a hazardous area or around explosive gasses or

vapours.

- Wear suitable personal protective equipment when working around or near

hazardous live conductors which could be accessible.

IPM 240 Series English

CAUTION

• Disconnect the test leads from the test points before changing the position

of the function rotary switch.

• Never connect a source of voltage with the function rotary switch in the

Ω, %, , µA, position.

• Do not expose the meter to extremes in temperature or high humidity.

• Never set the meter in Ω, %, , µA, function to measure the voltage of a power

supply circuit in equipment that could result in damage to the meter and the

equipment under test.

Symbols as marked on the Meter and Instruction

Unsafe Voltage

When the voltage measurement function “V” is selected, the “ ” symbol is displayed to

indicate the presence of a potentially hazardous voltage, when the tester detects a voltage

≧30 V or a voltage overload (OL)

Maintenance

Do not attempt to repair this meter. It contains no user serviceable parts.

Repair or servicing should only be performed by qualied personnel.

Risk of electric shock

SECTION 4- MEASUREMENTS

Making Basic Measurements

Before and after hazardous voltage measurements, test the voltage function on a known

source to determine proper meter functioning.

When connecting the test leads to the DUT (Device Under Test) connect the common test

lead before connecting the live lead; when removing the test leads, remove the live test

lead before removing the common test lead.

Voltage Measurement

Warning

To avoid electrical shock, hazard or damage to meter, do not attempt a measurement that

might exceed 1000 V DC or AC RMS. Do not apply more than 1000 V DC or AC RMS

between the common input terminal and earth ground.

Note - If the measured voltage is greater than 30 V DC or AC RMS, the display will show

the " " symbol.

IPM 240 Series English

Current Measurement

CAUTION

Do not measure current from the clamp jaw when a temperature probe is connected

to the meter.

- Do not clamp on to any conductor until the instrument is switched on.

- IPM241/242/244 have only AC current measurement mode.

- Auto torch light when clamping.

AUTO SENSE mode :

Display measurement result; AC only with RMS value or

DC value, whichever is greater.

AC mode : AC only with RMS value.

DC mode : DC value.

AC+DC mode : AC+DC RMS value.

Note

- Select " AC", " DC" or " AC+DC" indicator then press the navigator key to enter

the AC/DC/AC+DC mode.

- Select " AC"," DC" or " AC+DC" indicator then press the navigator key for more

than 2 seconds to return to the AUTO SENSE mode.

PEAK HOLD (AC mode only)

1. In ACV mode, select " " indicator on the display to enter PEAK HOLD mode.

To exit from PEAK HOLD mode, press the navigator key for more than 2 seconds.

2. In ACA mode, select " " indicator then press the navigator key for more than

2seconds to enter PEAK HOLD mode. To exit from PEAK HOLD mode, press

the navigator key for more than 2 second to return to the " " indicator.

IPM 240 Series English

In PEAK HOLD mode, the meter is activated to save the positive peak value and the

negative peak value. Positive peak value is displayed in PEAK MAX mode. Negative peak

value is displayed in PEAK MIN mode.

Inrush current : (AC mode only)

If inrush current during testing could be greater than 100A ac, select the range to

600A/1000A in advance before activating inrush current.
