KEY-FEATURES

Current pulse (square wave) 20 A / 50 A / 100 A
Rise time 15 ns – 80 ns (current dependent)
Accuracy ±2%
Frequency 0.5 Hz / 1 Hz
Remote control via USB or optional GPIB / IEEE interface possible

About the Probe Calibration Generator

The calibration generator KSZ 100D generates rectangular pulses of 20 A to 100 A with a pulse duration of 1 ms, or 0.5 ms at 100 A. The pulse current flows through a demountable current bar on the front panel. Current clamps and converters are contacted to this bar. Output current, pulse width and pulse period can be configured via remote control. The device is used for HF and DC control of current clamps and current transformers and due to the accuracy of its signals for calibration. Both calibration processes can be performed in one step only. Remote control via USB or GPIB interface is possible.

Functionality, Schematic

Functionality:	Schematic KSZ 100D:

The functionality of the KSZ100 D results of the schematic.
The pulse current is generated from a capacitor battery flowing through
a precise non-inductive resistor R1 and a fast switching transistor. The
value of the pulsed current is determined by the voltage U1 and the resistance R1. U1 is stabilized. At the contact bar a clamp device can be
connected.
Current transformers can be connected via power lead to the safety connectors.|

User Instructions

Do not switch output current while testing.
Make sure the Calibrator is set to Standby or turned off while removing or exchanging the contact bar.
Let the unit warm up by pulsing continuously for one minute prior to your tests. Follow the general instructions:

Turn on KSZ 100 D by pressing the switch at the backplate. The LED “PWR” at the front of the calibrator is blinking. While the rotary switch “Ip (A)” is set to standby no power is present at the contact bar.
Wait until the LED “200 V” is lit (approx. 30 seconds)
Connect the clamp or hall device to the contact bar. In case of hall devices remove the bar by EN pulling it slowly out of its sockets.
Connect trigger output to an oscilloscope if needed.
Set desired value on rotary switch “Ip (A)” The LED “PWR” is lit.
Activate switch “PULSE” to start the test. The red LED “PULSE” is blinking.

Interface Description KSZ 100D

The remote control commands for transfer via USB or optional GPIB / IEEE are based on the RS232 interface.

Configuration of the RS-232 interface

Baudrate: 19200	Data bits: 8	Parity: none	Stop bits: 1

Protocol

Communication takes place in a master-slave mode with KSZ 100 acting as slave. The KSZ 100 device responds to commands sent from outside. No communication takes place without such a command.
A binary protocol is used, where the length of each command is fixed. For each command there is a response with defined length. Since the number of bytes that must be transmitted for a specific command is defined, no control characters such as carriage return are needed to mark the end of a command.
The master must wait for the response after each command before the next command may be sent. The KSZ 100 device sends the response only when the command has been completely processed. The device is ready to receive a new command.

The following commands are defined:

Write register| Command:       ‘ R ‘
Answer:
nn:       Register number (8-bit)
lo, hi:    Value (16 bit), low and high byte
cs:       8 bit checksum
ans:     Answer code
6 = OK
7 = Error
---|---
Read register| Command:       ‘ r ‘
Answer:
ans:     Answer code
6 = OK
7 = Error
nn:       Register number (8-bit)
lo, hi:    Value (16 bit), low and high byte
cs:     8 bit checksum
Device info| Command:       ‘ I ‘
Answer:
ans:     Answer code
6 = OK
7 = Error
nn:       Info type
lo, hi:    Value (16 bit), low and high byte
cs:     8 bit checksum

Timeout

A maximum timeout of 1 second is allowed between two consecutive bytes. If the pause is longer, the command is aborted with an error message. The device is ready to receive a new command.

Calculation of Checksum

To check whether a command was transmitted without errors, all transmitted bytes except the response code are added up as an 8 bit number in the receiver. An overflow is ignored. In case of error-free transmission, the sum is 0.

Examples

Write access to register 4, Value is 2000:

Command:	‘R’ (0x52)
nn	0x04
lo	0xD0
hi	0x07
cs	0xD3

Read access to register 7, Value is 5000:

Command:	‘r’ (0x72)
nn	0x07
lo	0x88
hi	0x13
cs	0xEC
