Safety Information

Prevent personal injury, fire and product damage.
To avoid personal injury and to prevent fire or damage to this product or products connected to it, review and comply with the following safety precautions. Be aware that if you use this probe assembly in a manner not specified the protection this product provides may be impaired. Only qualified personnel should use this probe assembly.
Use only grounded instruments.
Connect and disconnect properly.
The KSZ10C Series has an 8 mF condensator battery which is charged to 200 V. The capacitor voltage of +200 V is applied between the red safety bar and ground. Make sure that the unit is turned off while removing or replacing the contact clip. Only use the unit with insulated leads.
Keep away from hazardous live circuits.
Avoid open circuitry. Do not touch connections or components when power is present.
Do not operate with suspected failures.
Indoor use only.
Do not operate the product in an explosive atmosphere.
About the KSZ 10C Series
The KSZ10C and KSZ10C/20A calibration generators are used for RF and DC control of current clamps and current transformers up to 10A or 20A. Furthermore, it can be used for calibration due to the accuracy of its signals. The execution of both calibration processes is possible in one operation. A current clamp can be clamped to the current bracket. Current transformers can be contacted by a current line at the safety sockets. The KSZ10 C or KSZ10C/20 A calibration generators contain a capacitor bank of 8 mF, which is charged to 200 V. The capacitor voltage is applied between the red safety socket + 200 V and ground.
When the device is switched on, 200 V are permanently present at the output socket. The device is not potential-free!
Switch off the device via the mains switch before contacting / decontacting the current bar. Operate the device only with fully insulated cables. Make sure that the respective safety regulations are observed.
Calibration
Before delivery, the KSZ10C series calibration generators are compared in terms of pulse and rise behavior with calibrated instruments whose calibration is traceable to DKD standards. Each calibration generator is delivered factory calibrated.
An annual calibration of the KSZ10C or KSZ10C/20A is recommended.

Functional Description

The function of the device can be seen from the principle block diagram. A pulse current is generated from the capacitor bank via an accurate, low- inductance resistor through a fast switching transistor. The value of the pulse current results from the values U1 and the resistance coefficient R1. U1 is stabilized.

Operation

Establish operational readiness, connect probe

1.  Connect the unit to the mains via a power cable to mains plug unit 11. (100 V – 240 V AC).

2. Insert the power bracket 8 into the safety sockets 5 and 7. If you are using a through-hole trans- former, plug it over the power bracket before switching on the unit.

3. Switch on the unit using the main switch (power plug unit) 11 on the back of the unit. The LED ‘PWR’ 1 lights up, the LED ‘TEST’ 4 flashes briefly.

4. After approx. 20 s the LED 6 ‘+200 V’ lights up and indicates that the capacitor bank is charged.
   The device is ready for operation.
   Set device, perform calibration procedure

5. Clamp a current clamp to the current bracket 8. If necessary, you can ground a current clamp via the ground socket 10.

6. Connect the trigger output 9 to your oscilloscope if you want to use the trigger function.

7. Set the current value with which you want to perform the test or calibration with the rotary switch 2. for calibration.
   Do not change the current value during the test procedure!

8. Before starting the test procedure: To avoid measuring deviations due to temperature drift, you should temperature drift, you should pulse the instrument continuously for one minute with the current value which you want to with the current value with which you would like to carry out the test/calibration. To do this, press the toggle switch ‘TEST’ 3. The ‘TEST’ LED 4 flashes. Only then begin the test procedure.

9. Start the test by pressing the toggle switch ‘TEST’ 3. The LED ‘TEST’ 4 flashes.

10. Trigger an oscilloscope until a pulse appears.

11. Calibrate the current clamp or transducer.

12. When the calibration is finished, release the toggle switch ‘TEST’ 3. ‘TEST’ 3. LED 4 stops flashing.

13. When the instrument is switched off via the mains switch, the capacitor bank is discharged via a discharge resistor within 2 s.

14. The mains fuse of 1A slow-blow is located in the mains plug unit 11 on the rear of the instrument.
