Frequently-asked questions

All our QUALISTAR products can be used to perform power surveys on single-phase and balanced or unbalanced three-phase systems: measurement of the current and voltage with calculation of the various power and harmonics values and the load factor of the source transformer.

The PEAK mode can be used to measure rapid variations in electric fields, whereas the standard mode is more representative of humans' exposure to electric fields and is therefore used most of the time.

The C.A 42 LF field meter provides the components according to 3 orthogonal axes "X, Y & Z" so that, by orienting the probe slightly to seek a maximum on one of these three axes, you can determine the orientation of an electric field.

The Ampflex sensor is a transformer designed according to the Rogowski-coil principle. The conducting carrying the alternating current to be measured forms the primary circuit, while the secondary is formed by a special winding on a flexible support. At it terminals, this winding develops a voltage proportional to the derivative of the primary current to be measured. This voltage is then carried by a shielded cable to the casing containing all the processing electronics and the battery power supply.

At startup, press MAX/MIN + A to modify the value of the current detection threshold for INRUSH measurement. The default values are 10%, i.e. 100 A for the F407 and 200 A for F607. The possible values range from 1% to 99%.

At startup, press 2nd + W. This will modify the recording interval in the EEPROM. The default value is 60 and the possible values range from 1 second to 600 secondes (i.e. 10 min).

For the first connection, you must enter the code 0000 in the Bluetooth manager window. Communication is then established automatically.

To return to the default configuration, enter the following Key-Switch combination: 2nd + A

To delete recordings from  the EEPROM (Electrically Erasable Programmable Read Only Memory), press 2nd + Ohm when you power up the clamps. No confirmation will be requested.

To check whether your sensors are connected correctly, the PEL Transfer software gives you access to the Fresnel diagram, in the "real-time data" section. This provides information on the connection of the voltage clamps and current sensors.

answered on 01/01/1970 :

In the "Configure the instrument" menu under the "Recording" tab, you can check the status of the SD card. This shows you the memory used and the memory remaining. It should be noted that the PEL can be equipped with an SD card of up to 32 GB. The card delivered as standard has a capacity of 2 GB.

The L642 is a temperature logger equipped with two input channels for J, K, T, N, E, R or S thermocouples. The sensors on these two channels must be similar. It is not possible to connect different thermocouples simultaneously to the L642 for recording.

answered on 01/01/1970 :

The power supply of your electrical distribution cabinet is three-phase so you are in CAT III with 600 V in relation to the earth in general, whereas your 230 V socket is CAT II. The HANDSCOPE proposes channels isolated from the earth and from one another up to 600V RMS in rfelation to the earth, so you can compare these two measurement points without worrying about any hazards.

answered on 01/01/1970 :

Doubleclick on channel A, B or M to mask the required channel. To unmask it it, click on the required channel for 2 seconds.

answered on 01/01/1970 :

We propose a miniFLEX MA100 clamp for the 100 A current measurement on one of the channels and for direct 230 V voltage measurement on the other channel. If you select multimeter mode with the power function, you can choose your single-phase assembly. You then obtain an active power measurement in VA and, if you select "SURV", you obtain the MIN/MAX/AVG values and the trend of this power value.

NOCT corresponds to the nominal operating temperature of the cell. GAMMA is the power coefficient in relation to the PV module's temperature. These two values are supplied by the solar-panel manufacturers.

You may obtain 2 different files if the camera provides the real image as well as the infrared image. The .CCD files are "real image" files, while the .SAT files are "infrared image" files.
