1 General description
WARNING!
WARNING!
The devices induce output voltages and currents which conformable to EN61010-1 are not
dangerous to life. But it is possible that they effect health damages to sensitive persons.
ATTENTION!
ATTENTION!
The devices must only be used in combination with iseg approved crates.
The iseg NHR modules are multi-channel high voltage power supplies in 1/12 NIM standard cassette format.
The NHR provides up 4 channels, each with an independent voltage and current control and electronically reversible
polarity. The 6kV channel provides a maximum versatility: with three electronically switchable HV-output modes it can
supply 4mA up to voltages of 2kV, mA up to 4kV and 2mA up to 6kV. Alternatively the NHR can be equipped with cost
efficient 2kV/6mA channels.
Several NHR modules can be daisy-chained by CAN and controlled with a single USB connection or by an iseg iCS system.
The hardware is made of best components such as 24 bit ADC and 20 bit DAC, the approved front panel control of the
NHR series with TFT display allows user-friendly intuitive operation.
The NHR is equipped with a comprehensive set of security features like overvoltage and short circuit protection,
hardware limits and much more.

3 Handling
3.1 Connection
The supply voltages are connected to the module via the NIM-connector on the rear side of the module. An USB
connector and two ,5mm audio jack connectors for the CAN interface are located on the front panel. The second CAN
connector can be used to daisy-chain several NHR and/or NHS modules.

Display shows monitor and control values
Rotary encoder with push button to navigate in menu and set values
LED „OK“ signals condition of the corresponding channel
LED „HV ON“ signals a measured output voltage at the corresponding channel
LED „POS“ and „NEG“ indicate the selected polarity of the corresponding channel
On/Off switches to turn the corresponding channel on or off
Hardware limit set screws Vmax and Imax to set the maximum output voltage or current
relatively to the absolute maximum values of the channel (Vnom / Inom)
USB and Safety Loop connector
CAN connectors
Single channel Inhibit connector

3.2.1 Main Screen (Channel List)
After start up of the NHS the display will show a Main screen similar to the following image which consists of 5 elements:
1 Left function button: main menu
Shows the function of the left button. If the user pushes the left button in Main screen, the display will show the Menu
screen.
2 Right function button: display mode
If the user pushes the right button in Main screen, the Main screen will switch to the next display mode, which is shown
directly above the channel list.
Following display modes are available:
1. VI-MEAS →voltage and current – measured values
2. VI-SET →voltage and current – set values
. V-MS →voltage – measured and set values
4. I-MS →current – measured and set values
5. INFO →maximal values of the selected output mode
3 Channel numbers and running states
This is part of the channel list (4) and shows the corresponding channel number. The background color signals the
running state of each channel. The background colours means the following:
Black →the channel is switched off
Green →the channel is switched on
Yellow →the channel is switched on but no regulation (CV, CC) is active
Orange →the channel is switched on but has unmasked error event(s)
Red →the channel has at least one masked error event
4 Rotary encoder button function
If the user presses the button of the rotary encoder, the menu will switch to the channel menu of the marked channel.
5 Channel list and rotary encoder function
The channel list shows-dependent on the display mode-measure and/or set values of voltage and current for each
channel.

In display mode VI-MEAS the following can be seen:
If a channel is switched off, the values of Vmeas and Imeas are grey.
If a channel is in constant voltage regulation, Vmeas value is white and Imeas value is grey
If a channel is in constant current regulation, Vmeas value is grey and Imeas value is white
The channel row which is slightly brighter (in image channel 4) is the marked channel by the rotary encoder. Turning the
rotary encoder counter-clockwise will mark the channel above the current channel and turning clockwise will mark the
channel below the current channel.

3.2.2 Menu Screen
By pressing the left button in Main screen, the display will switch to the menu screen, that looks similar to the image
below:
The menu screen shows menu entries to set up behavior and check information of the device hardware.
To enter a menu entry, the user has to mark an entry by turning rotary encoder and then pressing the rotary encoder
button. The selected entry is then shown in the menu path.
