ENTERING TRANSIENT MODE VALUES
Example:
The test application requires the main operation to be at 25 A in CC mode and a Transient test current of 50.0 A,
Frequency of 500Hz, Slew rate of 5 ms, and a 50% Duty cycle.
1. Set the Transient operation mode to Continuous by pressing the CONT Hot Key.
2. Set CC mode – press the CC hot key.
3. Set main voltage level – press and hold the encoder, the voltage value on the LCD will flash and enter 25.0 A. After
you have entered the new current value (25.0) press ENTER to confirm.
4. Set Transient voltage value - press the PEAK hot key to enter transient voltage edit mode and view stored current
value. Press and hold the encoder and the transient current value will flash on the LCD, and enter 50.0 A. After you
have entered the new current value (50.0) press ENTER to confirm.
5. Set transient Frequency - press the FREQUENCY hot key, tap the encoder to edit or change stored value to 500 Hz
then press ENTER to confirm.
6. Set transient Slew rate - press the SLEW hot key and use the encoder " 43" to scroll to Rise time and tap the encoder
to edit or change stored value to 5 ms then press ENTER to confirm.
7. Repeat for Slew Fall Time
8. Set transient Duty Cycle - press the DUTY hot key and tap the encoder to change the duty cycle to 50%, then press
ENTER to confirm.
9. Press the CONT hot key to select the Continuous Transient Operation mode.
10. Activate the Continous Transient operation by pressing the PULSE hot key and the INPUT hot key.
The Transient condition will cycle continuously based on the rise and fall slew time until the CONT transient operation is
turned off. By changing the frequency, the transient cycle will increase or decrease in repetition based on the set value.
TRANSIENT FREQUENCY, SLEW RATE AND DUTY CYCLE PROGRAMMING
The transient frequency, slew rate and duty cycle can be programmed directly using the Hot Keys.
1.
Press the “FREQ”, “SLEW” or “DUTY” hot key to access the transient frequency, slew rate and duty cycle editing
mode and LCD module will display the most current setting once the designated hot key is pressed.
2. To change existing values to the appropriate parameter, tap the encoder to activate the edit entry mode.
3. For Frequency editing, the LCD module will display the following:
FREQ = 1000 Hz
4. Enter the following numerical keys “2”, “0”, “0”, “.” and “0” keys in sequence in order to change the Frequency to
200Hz.
5. Make sure that the entered number is correct and press “ENTER” key to complete the entry operation.
6. Press “CLEAR” key to return to the metering mode. By pressing the "Clear" with no entry will display AMREL Model
number and software version.
