Getting Started
4. Check whether the power voltage matches with the supply voltage. Please
refer to 2.4 Connecting the Power Cord to select proper AC input.
5. After multiple units are connected in parallel and powered on, the error re-
lated to the fiber-optic is indicated. Please refer to the following steps for
troubleshooting.
• FIBER MULTI MASTER: Multiple units (with panel) are connected in par-
allel, please confirm whether multiple Masters are set. Select System→-
Parallel menu to reset. There can only be one single unit as the Master,
and the other single units must be set to Slave. After the setting is com-
pleted, power off and restart each single unit.
• FIBER EXT UNLOCK: Multiple units (with panel) are connected in paral-
lel, check whether the cable connection of the fiber outer ring (TX and
RX) is closed. Then confirm that whether the System→Parallel menu is
set. There can only be one single unit as the Master, and the other single
units must be set to Slave. After the setting is completed, power off and
restart each single unit.
• FIBER INNER UNLOCK: Only one master unit (with panel) and the rest
is slave unit (without panel) connected in parallel, firstly, confirm whether
the cable connection of the fiber inner ring (F-TX and F-RX) is closed.
Then confirm that whether the System→Parallel menu is set. If yes,
please restore the setting to Single mode, then power off and restart.
Then consult ITECH technical support engineers for the parallel setting
method in this case.
6. If the instrument still does not start, contact ITECH technical support
engineer.
3.2 Set Output Value
The voltage value, current value, power value can all be programmed. The user
can set different output parameters within the range of specifications according
to the need to satisfy a range of test requirement.
After selecting the operation mode, the interface displays the setting value
under the selected operation mode and the cursor blinks to prompt. The user
can use the following methods to set the values.
• Directly use the number keys to set the value.
• Rotate the knob to set the data in the cursor position. Rotate the knob clock-
wise to increase the set value and anticlockwise to decrease the set value.
Once the data in the cursor position increases to ten, the value will add one
