4.5.9 Transient Reference (Trans. Ref.)
The Transient Reference parameter sets the nominal voltage used for a transient detect
reference.
1. In the Setup Mode, use the up and down arrow keys to scroll to the TRANS REF field.
2. Press SHIFT, the display "SHIFT1" will switch ON
3. Use the ▲ or ▼ keys to select the desired voltage reference (from 50.0V to 850.0V)
4. Press SHIFT again to return to Setup Mode editing or press EXIT to leave the Setup mode.
4.5.10 SDVP (Swells/Dips Voltage)
The SDVP parameter sets the upper and lower limit range (in %) for the transient voltage
detection. For example, if the Transient Reference is set to 200V and the SDVP is set to 10%,
the SDVP range will be 180V to 220V.
1. In the Setup Mode, use the up and down arrow keys to scroll to the SDVP field.
2. Press SHIFT, the display "SHIFT1" will switch ON
3. Use the ▲ or ▼ keys to select the desired voltage threshold (1% to 100%)
4. Press SHIFT again to return to Setup Mode editing or press EXIT to leave the Setup mode.
4.5.11 SD Card Numerical Format (USA or European)
Note: SD Memory Cards default to the basic numerical format (USA) whereby a period is used
to separate units from tenths, for example: 20.00. European formatting uses a comma, for
example: 20,00.
1. In the Setup Mode, use the up and down arrow keys to scroll to the DECIMAL field.
2. Press SHIFT, the display "SHIFT1" will switch ON
3. Use the ▲ or ▼ keys to select the desired format (USA or EURO)
4. Press SHIFT again to return to Setup Mode editing or press EXIT to leave the Setup mode.
4.5.12 Set Clamp type
1. In the Setup Mode, use the up and down arrow keys to scroll to the CLAMP TYPE field.
2. Press SHIFT, the display "SHIFT1" will switch ON
3. Use the ▲ or ▼ keys to select the appropriate clamp type.
4. Press SHIFT again to return to Setup Mode editing or press EXIT to leave the Setup mode.
4.5.13 Set Current Range
ATTENTION: Ensure that the 'A' range setting matches the attached clamp's rating
1. In the Setup Mode, use the up and down arrow keys to scroll to the "A RANGE" field.
2. Press SHIFT, the display "SHIFT1" will switch ON.
3. Use the ▲ or ▼ keys to select the current range.
4. Press SHIFT again to return to Setup Mode editing or press EXIT to leave the Setup mode.
