8.6.- CLOCK
Make sure that the correct time has been programmed before the analyzer's programming procedures
have been completed. Use the analyzer's WEB server (see corresponding section) or the specific
CIRCUTOR software to make sure that the correct time has been programmed in the analyzer.
QNA500 offers the Local Time or UTC Time options.
8.7.- BATTERY
M-BASE module has an internal battery that can be used to power all connected modules. The main
purpose of this battery is to make sure that all modules continue to operate during a limited period of
time in case there is an interruption in the electric supply.
The most common function entails storing voltage sags or interruptions, and moreover keep active the
communication with the device or perform certain operations (activate/deactivate loads).
The main feature of the products of the MULTIFIT range is based on the connection of said products to
the same M-BASE module, which will operate as independent products. The battery can power the
modules connected to the system during a period of time configured by the user. The default time is 1
minute and it can be configured to up to 15 minutes. The M-BASE module can power a maximum of 2
QNA500 modules + 1 M-8IO module simultaneously with the battery.
8.8.- STANDARD RECORDING PERIOD
The recording period shows the number of minutes that QNA500 8IO uses to create a new register in
the memory. All electrical parameters will be recorded (only those selected) at the end of the
programmed time. Average, maximum and minimum values obtained during this period of time will be
recorded. The default recording time is 10 minutes. This value can be modified to a period of between
1 minute and 2 hours. This time only affects the data file (.STD).
8.9.- ENERGY RECORDING PERIOD
The recording period shows the number of minutes that QNA500 8IO uses to create a new register with
energy values in the memory.
8.10.- SELECTING VARIABLES TO BE RECORDED
QNA500 analyzer can be used to select the variables that will be recorded. These variables can be
selected via the WEB server (see the corresponding section in this manual) or via specific CIRCUTOR
software.
