AMPROBE

MULTITEST2000

CAUTION

For recordings (ANALYSIS and AUX function) ALWAYS use the external power supply adapter (optional code A0050) even the instrument allows the operator to perform a recording using internal batteries. If during a recording the external power supply adapter is de-energized, the instrument will continue the recording using the internal battery power until the batteries are exhausted (the data stored up to the point the instrument shuts down won’t get lost). Because of this we recommend you ALWAYS insert a new set of batteries before a long recording.

The instru ment uses soph i sticated al gorithms to prolong the battery life. Specifically:

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

connected), after about 5 minutes from the last key press 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 press 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 fulfils the technical specifications listed in this manual. The performance of the specifications is guaranteed for one year.

3.4. STORAGE

In order to maintain the accuracy of the measurements, after a period of storage in extreme environmental conditions, wait the necessary time for the apparatus to return to normal operating conditions (see environmental specifi cations listed in parag rap h 14.4).

6. SAFETY TEST FUNCTION S

6.1. LOWΩ: CONTINUITY TEST WITH 200mA TEST CURRENT

The measurement is taken according to EN 61557-2 and VDE 0413 part 4.

WARNING:

Turn the rotary knob to the LOWΩ position.

This key allows the operator to select one of the following measuring modes:  AUTO mode (the instrument carries out two measurements with reversed

polarity and displays their average value). This mode is recommended for the continuity test.

 RT+ mode (measurement with positive polarity and the ability to set the

duration time of the test). In this case the operator can set a measuring time long enough to permit them to move the protective conductors while the instrument is carrying out the test so as to detect any bad connections.

 RT- mode (measurement with negative polarity and the ability to set th e

duration time of the test). In this case the operator can set a measuring time long enough to permit him to move the protective conductors while the instrument is carrying out the test so as to detect any bad connection.

This key permits the operator to perform a calibration (compensation for the resistance of the cables used for the measurement).

Before carrying out the continuity test be sure that there is no voltage at the ends of the conductor under test.

N.B.

If the resistance is lower than 5Ω (including the resistance of the calibration) the

continuity test is executed by the instrument with a test current higher than 200mA.

AMPROBE

A numerical value in this field means that the instrument has been calibrated; this value remains on

the display for any further measurement

even though the unit is switched off and on again.

5. At the end of the test the result is stored and used as OFFSET (that is to say that it is subtracted from any continuity test carried out) for all the subsequent measurements.

Note

: The instrument performs the calibration only if the resistance of the test leads is

lower than 5Ω.

AMPROBE

MULTITEST2000

TEST LEADS Before each measurement always assure that the

calibration is for the cables in use. During a continuity test, if the resistance value free of calibration (that is the resistance value less the calibration offset value) is negative, the symbolν is displayed. Probably the calibration resistance value stored in the instrument memory is not for the cables in use, therefore a new calibration must be performed.

6.1.1.1. Procedure to reset test leads calibration parameters



To cancel calibration parameters it is necessary to perform a

calibration procedure with a resistance of test leads higher than 5Ω (for example with

open test leads). When a cancellation is effected

This function allows the following operat ions:  display in real time the electrical parameters of a single phase systems (with and

without neutral wire) and the harmonic analysis of voltage and current.

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

instrument input generating a "Smp" record inside instrument memory. It will be possible to analyse the memorized data ONLY by transferring it to a PC.

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

of voltage, current, corresponding harmonics, active, reactive and apparent powers, power factors and cosϕ, active, reactive and apparent energies, voltage anomalies (voltage sag and surge) with 10ms resolution. It will be possible to analyse the recorded data ONLY by transferring them to a PC.

It's fundamental the In strument settings correspond to th e Installation type under test and accessories is use. For this we recommend you to check instrument's setting before execute an ANALYSIS measurement.

8.1.1. Type of electrical system under test

The parameter SYSTEM is fixed to "SINGLE" value as Multitest 2000 is able only to analyse Single Phase system.

8.1.2. How to set the fundamental frequency Position the cursor on the corresponding word by pressing the multifunction keys F1 and F2 and select the network frequency between the possible values 50Hz and 60Hz by

pressing the multifunction keys F3 and F4. This parameter is important ONLY if the input voltage is not sufficient to recognise 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.

AMPROBE

MULTITEST2000

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

parameter must be equal to the scale selected on the clamp. Set the desired value by pressing the multifunction keys F3 and F4.

AMPROBE

MULTITEST2000

8.1.4. How to set the Clamp Type

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

 STD: for Standard clamps or Current Transformer  FLEX: for Flexible clamps.

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

8.1.5. 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 he 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 none transformer systems. Select “TV RATIO” in the ANALYZER CONFIG menu. Set the desired value by pressing the multifunction keys F3 and F4.

8.1.6. How to enable/ d i s able the pass word

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 po ssible 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):
