does not require any special maintenance. Simply comply with the common rules that apply to any
electronic device:
●
Clean the instrument with a soft and clean cloth (the edges must not be frayed).
●
Do not use detergents or corrosive or abrasive substances.
●
Do not store the instrument in areas where the humidity and temperature levels exceed the ranges
prescribed below.
6.1 - Accuracy Check
The manufacturer cannot determine in advance the frequency at which an accuracy check should be performed,
as instrument performance will depend on the conditions of use (heavy- or light-duty, environmental conditions,
etc.).
Therefore, the user should perform periodical performance checks, using a sample instrument (of a higher
category). At first, accuracy checks should be performed yearly, and thereafter increased or decreased based on
the outcome of the checks.
If new calibration is required, the instrument can be sent to the manufacturer's in-house laboratory.
If deemed appropriate, the user can also request that the manufacturer perform the accuracy check.
NOTE
: the in-house calibration laboratory of Elcontrol Energy Net is currently the only authorised calibration
centre used.
6.2 - Repair

is a sophisticated electronic product designed by Elcontrol Energy Net.
Any attempt to repair the instrument without the necessary know-how may pose a safety risk.
Therefore, no unauthorised personnel or laboratories should carry out repair, maintenance or calibration
operations. The warranty shall no longer be valid if the instrument is tampered with by third parties.
6.3 - Troubleshooting
●
Instrument will not switch on.
The battery has run out. Connect instrument to power supply.
●
Instrument does not perform correct measurements.
Make sure the current and voltage ratios match the current clamps and VTs connected to the system (Sect.
4.2.1 and 4.2.2).
Make sure the current clamps are not connected inversely (Sect. 4.2.1.6).
Make sure the phase sequence is correct (Sect. 4.2.1.6).
●
The display is blurry.
Check the brightness and contrast levels of the LCD (Sect. 4.2.6.3).
●
The display dims after a few seconds.
Check the screensaving settings (Sect. 4.2.6.1).
●
The display stays on permanently, even though it has been set-up differently.
Check if a video alarm is present (Sect. 4.2.12).
●
Certain pages or entire menus are not displayed.
Make sure the menu type is set on Full and not Partial (Sect. 4.2.6.4).
Make sure the connection type set is correct (Sect. 4.2.1.1).
●
A significant number of alarms have gone off.
Make sure a suitable alarm hysteresis has been set (Sect. 4.2.12.1).
