About the TK100C Probe Calibrator TK100C
The TK100C facilitates DC, LF and HF adjustment of HV-probes.
Mode of operation
The function of TK100C can be seen from the circuit principle.
A stabilized 100 V DC source loads a 1 uF capacitor. A "none chatter contact" connects the voltage to a RC
network of approx. 50 Ωand 47 pF. The rise time between 10% and 90% is approx smaller 6 ns. The duration
of the square wave pulse is 5 ms.
For optimum results the HV-probe or divider should be connected coaxial.

How to use this instrument TK100C
Setup:
1. Connect the probe calibrator to the power supply and the power supply to mains.
NOTE: The Power LED (2) is lit,
The Mode Indicator LED (3) is off.
There is no voltage applied to the BNC Output (4)
2. Connect the probe to the BNC jack of the measuring instrument and adjust the scope-to-probe
divider ratio.
4. Connect the probe to the BNC Output (4) of the TK100C
Operation:
- By pressing the Mode Button (5) once, the TK100C provides a 100 V square wave signal of 5 ms duration.
NOTE: The TK100C is in pulse mode. The Mode Indicator LED (3) blinks.
- By pressing the Mode Button (5) again the TK100C is set to DC Mode, providing 100 V DC
NOTE: The Mode Indicator LED (3) glows constantly.
- If the Mode Button (5) is pressed again the TK100C will go into Standby once again.
NOTE: The Mode Indicator LED (3) is turned off again.
Make sure to set the trigger level at the scope to a decent value for best results.

Calibration TK100C
The output voltage of the TK100C can be adjusted.
On the bottom side of the device is a trimmer potentiometer located under the identification label.
It is marked by the "DC Adjust" symbol.
Please note, that any previous calibration is invalidated by adjustments you make to this trimmer.
Safety Precautions & Override
The TK100C has a safety circuit inside, wich enables output voltage only if a BNC Adapter is connected.
You can override this safety feature at your own risk following these steps:
1. Disconnect the TK100C from the 15 V DC supply voltage.
2. Wait for at least 20 seconds.
3. Hold down the Mode Button (5) while reconnecting the 15 V DC supply voltage.
The safety circuit is now circumvented.
You can reenable the safety circuit by repeating the steps above, once again.
