2. GENERAL DESCRIPTION

2.1. INTRODUCTION

The DM-IIIS represents a new approach to the world of electrical measurement. Computer assisted instruments such as the DM-IIIS permit an easy and fast analysis of a huge quantity of data.

2.2. FUNCTIONS

The DM-IIIS is able to:  display in real time the electrical parameters of a single phase and three-phase

systems (with or without neutral wire) and the harmonic analysis of voltages and currents.

 conduct a direct Energy measurement (without memorizing).  memorize (pressing SAVE key) the sampled values of the Parameters present at the

instrument’s input generates a "Smp" record inside the instrument’s memory. It will be possible to analyze the memorized data ONLY by transferring it to a PC.

 record simultaneously (pressing the START key after a proper setting): RMS values

of voltages, currents, corresponding harmonics, active, reactive and apparent powers, power factors and cos, active, reactive and apparent energies, voltage sag and surge with 10ms resolution. It will be possible to analyze the recorded data ONLY by

transferring them to a PC.

2.3. INITIAL SCREEN

When turning on the instrument by pressing ON/OFF, this screen will appear for a few seconds:

Here you can see:

 serial number of the instrument (SN.:)  firmware software release (VER.:)  calibration date (CALIBRATION:)  transmission speed through serial I/O (Baud Rate)

CAUTION

For recordings ALWAYS use the external power supply (even though the instrument allows the operator to perform a recording using internal batteries).

3. PREPARING THE INSTRUMENT

3.1. INITIAL CHECK

This instrument has been checked before shipment from an electrical and mechanical point of view. All possible precautions have been taken in order to deliver it in perfect condition. Notwithstanding, on receipt of the instrument we suggest that you check it summarily to make sure that no damage has occurred in transit. Should you find irregularities please contact the carrier immediately. Furthermore, please make sure that the parcel contains all the accessories and parts listed in paragraph 13.3. In case of discrepancies please contact your dealer. Should it be necessary to return the instrument to the supplier please keep to the instructions given at paragraph 17.

3.2. INSTRUMENT POWER SUPPLY

The instrument can be powered by:

 6 batteries 1.5V AA - LR6 series located in the compartment on the back of the

instrument

 an external power supply code DMT-EXTPS supplied with the instrument (standard

accessory).

The instrument uses sophisticated algorithms to prolong the battery life. Particularly:

 The instrument switches OFF the backlight Automatically after 5 seconds.  If the instrument is displaying in real time (and the external power supply is not

connected), after about 5 minutes from the last key pressure or switch rotation the instrument turns off automatically ("AUTOPOWER OFF" procedure).

 If the instrument is recording or is measuring energy (and the external power supply is

not connected), after about 5 minutes from the last key pressure or switch rotation the instrument starts a special procedure to save the batteries ("ECONOMY MODE"): the instrument keeps recording but the display is turned off.

3.3. CALIBRATION

The instrument complies with the standards mentioned in this manual. Its performance is guaranteed for one year from the purchase date.

pressing the multifunction keys F3 and F4. This parameter is important ONLY if the input voltage is not sufficient to recognize the value of the frequency (for example, only the clamps for the current measurement are connected). In this case the instrument generates an internal synchronism equal to the value of the set frequency.

5.2.3. How to set the current range The value of this parameter must be always equal to the full scale of the current clamps used to take the measurement. In case multi-scale clamps are used, the value of

this parameter must be equal to the scale selected on the clamps. Only for FLEX3 clamps You can set this parameter to 1000A or 3000A without any adjusting in the clamps. The instrument automatically will change its sensitivity according with settings. Set the desired value by pressing the multifunction keys F3 and F4.

DMIIIS

paragraph 16.3.2)

DMIIIS

EN - 11

5.2.4. How to set the clamp type

The value of this parameter must always be equal to the clamp type you are using. Two types of clamps are available:

 STD: for Standard clamps or Current Transformer  FlexEXT: for Flexible clamps with external power supply  FlexINT: for Flexible clamps FLEX3 (coil directly connected with instrument's

inputs). These clamps allows 1000A and 3000A range.

Set the desired value by pressing the multifunction keys F3 and F4.

5.2.5. How to set the value of the transformer voltage ratio (TV RATIO)

The instrument can also be interfaced with step-down transformers in the equipment under test: it can display the value of the voltages present on the primary winding of these

transformers. To do this it will be necessary to set the value of the transformers’ windings

ratio from 2:1 to 3000:1. The default is set at 1:1 for measurements of non-transformer systems.

Select “TV RATIO” in the ANALYZER CONFIG menu. Set the desired value by pressing

the multifunction keys F3 and F4.

5.2.6. How to enable/disable the password

The instrument is provided with a protective routine to avoid the risk of being disturbed or interrupted during a recording or an energy measurement. Once a recording or a direct

energy measurement has been started (with the option “PASSWORD” enabled), after

about 3 minutes from the last key pressure or switch rotation it won’t be possible to press

START/STOP to stop the recording, “PASSWORD” will be displayed and it will be

necessary to insert the password. In order to insert the password (which is not changeable), press the multifunction keys in the following sequence (within 10 seconds):

F1, F4, F3, F2

If you wait more than about 10 seconds the display will return to the meter mode and the

instrument will continue recording. If you insert a wrong password the message “Password error” will be displayed under “PASSWORD”. After a few seconds the display will return to

meter mode and the instrument will continue recording. In order to enable/disable this option the correct password will have to be entered. The display will return to meter mode and START/STOP will have to be pressed again to stop the recording. You will then need to re-enter the “ANALYZER CONFIG” menu and scroll up or down to the item “PASSWORD: ON” using the multifunction keys F1 and F2. Then turn the password off by pressing the multifunction keys F3 and F4.
