ELR 9000 HP Series
Setting P. Description
Enable R mode 7 Activates (“ Yes ”) or deactivates (“ No ”) the internal resistance control. If activated,
the resistance set value can be adjusted on the main screen as additional value.
For details refer to „3.2.3. Resistance regulation / constant resistance“
USB file separator format 8 Switches the decimal point format of values and also the CSV file separator
for USB logging (see
1.9.6.5
and
3.4.10
), as well as for other features where
a CSV file can be loaded
US = Comma separator (US standard for CSV files)
Default = Semicolon separator (german/european standard for CSV files)
USB logging with units
(V,A,W)
8 CSV files generated from USB logging by default add physical units to values.
This can be deactivated by setting this option to “ No ”
Calibrate device 9 Touch area “ Start ” starts a calibration routine (see
„4.3. Calibration“
), but only
if the device is in U/I or P/I mode.
Reset device to defaults 10 Touch area “ Start ” will initiate a reset of all settings (HMI, profile etc.) to factory
default, as shown in the menu structure diagrams on the previous pages
Restart device 10 Will initiate a warm start of the device
Master-Slave mode 11 Option “ OFF ” (default) disables the master-slave mode (MS), while options
MASTER or SLAVE set the device to the selected position. For details about
the MS mode see section
„3.11.1. Parallel operation in master-slave (MS)“
PSI / ELR system 11 Only displayed if the device has been set to MASTER
When activated by finger touch (check mark), it determines that the power sup -
ply is part of a two-quadrant operation (see
„3.11.3. Two quadrants operation
(2QO)“
) system and thus it will be master on the Share bus, which is required
for a 2QO, because in that mode the power source unit has to be master
Repeat master init. 12 Touch area “ Initialize ” will repeat the initialisation of the master-slave system
in case the automatic enumeration of the slave units by the master is once
unsuccessful so the system would have less total power than expected or has
to be repeated manually in case the master unit couldn’t detect a missing slave
3.4.3.2 Menu “User Events”
See
„3.6.2.1 User defined events“ on page 62 .
3.4.3.3 Menu “Profiles”
See „3.9 Loading and saving a user profile“ on page 64 .
3.4.3.4 Menu “Overview”
This menu page displays an overview of the set values (U, I, P or U, I, P, R) and alarm settings as well as adjust-
ment limits. These can only be displayed, not changed.
3.4.3.5 Menu “About HW, SW...”
This menu page displays an overview of device relevant data such as serial number, article number etc., as well as
an alarm history which lists the number of device alarms that probably occurred since the device has been powered.
3.4.3.6 Menu “Function Generator”
See „3.10 The function generator“ on page 65.
3.4.3.7 Menu “Communication”
This submenu offers global and specific settings for digital communication via the built-in USB interface and the
optional modular interfaces of the IF-AB series or the optional GPIB port. The button which is labelled with the
interface name opens one or more settings pages, depending on the interface in use. There is furthermore an
adjustable communication timeout for USB and Ethernet, to make it possible to successfully transfer fragmented
messages (data packets) using higher values. In the screen for “Com Protocols” you can enable both or disable
one of the two supported communication protocols, ModBus RTU and SCPI. This can help to avoid mixing both
protocols and to receive unreadable messages, for example when expecting a SCPI response and getting a Mod-
Bus RTU response instead.
For all Ethernet interfaces with two ports: „P1“ is related to port 1 and „P2“ to port 2, like printed
on the module face. Two-port interfaces will use one IP only.
