Figure 14.3K Jumper Configuration For Applying External Voltage To Sample (For Systems With The Basic Extender Module) - Veeco 004-210-000 Instruction Manual

External Voltage Source Applied to the Sample
In some cases, it may be advantageous to utilize voltages greater than 12 VDC, or to utilize a pulsed
power supply. If an external source of voltage is to be applied to the sample, configure jumpers as
shown in Figure

A current-limiting resistor (e.g., 10-100MΩ) should be placed in series with the external voltage
supply as shown to protect the tip and sample from damage. Current-limited power supplies may
also be used. Voltage leads should be connected to pins on the header using soldered, push-on
connectors. Do not solder leads directly to the header pins, as the heat may cause damage and/or
make jumpering the pins difficult.
