SAFETY INFORMATION

Safety Information

Read and understand this Instruction Manual completely before using this instrument. Failure to observe the warnings and cautions in this Instruction

Manual may result in injury, death, or damage to the instrument and other equipment or property.

If this instrument is used in a manner not specied in these instructions, the protection provided by the instrument may be impaired.

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 fingers behind the finger 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 current 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 blown fuse with the correct type and rating as specified in this Instruction Manual•

Use caution when measuring voltages above 30V ac rms or 60V dc. These voltages pose a shock hazard•

To avoid incorrect readings that can lead to electric shock, replace the battery as soon as low battery indicator • appears in the display

Disconnect the circuit power and discharge all high-voltage capacitors before making resistance, 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•

When this instrument is powered from a Mains power source, the Protective Conductor Terminal must be connected to Ground•

Before powering this instrument from a mains power source, ensure the mains input voltage selector is set to the correct position•

 CAUTION

Disconnect the test leads from the test points before changing the position of the function rotary switch•

Never connect the instrument to a source of voltage with the function rotary switch in Ω/• /A//Hz position

If possible, do not work alone, so assistance can be given if required•

Do not expose the instrument to extremes of temperature or high humidity•

When connecting the test leads to a circuit or device, connect the black lead before the red lead and disconnect the red lead before the black lead•

If the instrument is used near equipment that generates electro-magnetic interference, the display may be unstable or indicate incorrect measurements•

When measuring current using the 10A range, the maximum measurement duration is 30 seconds in any 10 minute period for currents greater than 10A •

INTRODUCTION

2. Introduction

The ISO-TECH IDM 201N Multimeter is a versatile and portable bench-type instrument suitable for workshop and laboratory based engineers and

technicians, as well as eld-service engineers who require a self-powered instrument for maintenance, test or repair activities. The instrument may be

powered from an ac mains supply between 90V ac and 263V ac, or by internal batteries as required. An integral compartment provides stowage space

for test leads, spare batteries and fuses. The instrument uses a 3½ digit (2000 count) backlit Liquid Crystal Display with annunciators, polarity and

automatic decimal point placement. The auto-range function may be disabled for convenience and Maximum/Minimum and data-hold functions can

also be selected if required. The measurement capabilities are as follows:

DC and AC voltages•

DC and AC current•

Resistance and continuity checking•

Capacitance and Diode testing•

Frequency •

Unpacking and Inspection

Unpack the multimeter and check the contents for damage. If any items are damaged or missing, contact the supplier.

The instrument is supplied with the following items:

1. The Digital Multmeter.

2. One pair of Test-leads (one red lead and one black lead).

3. This Instruction Manual.

4. One UK-style mains power cable.

5. One Schuko style mains power cable.

6. One Carrying-strap.

7. One pair of Alligator-clips (One red clip and one black clip)
