External trigger source requirements
The external trigger source must use TTL levels:
low level 0-0.4 V
high level 2.4-5.25 V
min. current of trigger source 3 mA
The DC- STIMULATOR works:
- with level detection (not edge detection)
- with "active high" , i.e. stimulations are started by high levels
The trigger level must last for a minimum of 1 ms .
Cleaning the device
Clean the DC- STIMULATOR using a cloth slightly dampened with water. For the display a
standard commercial TFT display cleaner should be used. Spray some cleaner on a soft
and clean cloth before wiping the display gently.
Never spray cleaner directly onto your DC- STIMULATOR and never let liquid run
into the device. Never use harsh or caustic chemicals to clean the DC-
STIMULATOR . The manufacturer accepts no responsibility for any damage
caused by such use.
In general, disinfection of the system beyond normal cleaning is only necessary if people
from high-risk groups (e.g. drug users) are in contact with it. In this case, the careful use of a
common disinfection product is recommended to ensure user protection. Wipe the surface
of the DC-
STIMULATOR and the electrode cables / supply cables with your disinfection
product (e.g. 90 % alcohol).
