⚫ Manual: if [Trig] on the front panel is pressed in the valid manual trigger
mode, the load will be triggered once.
⚫ Bus: if the bus trigger command is received by the load in the valid bus
trigger mode, the load will be triggered once.
⚫ Trigger1: if one trigger signal is connected to the Digital IO-6 of digital I/O
Interface terminal on the rear panel, the load will be triggered once.
⚫ Trigger2: if one trigger signal is connected to the Digital IO-7 of digital I/O
Interface terminal on the rear panel, the load will be triggered once.
6.9 Query the System Log
The IT8200 series instrument provides the system operation Log query function.
On the Menu interface of the front panel of the instrument, click Log or directly
press Shift +1[Log] to enter the Log query interface. You can view historical
system operation records on this screen.
6.10 Query the Energy
IT8200 series instrument provides the energy statistics function. Click WHours
button in the Menu interface of the front panel of the instrument to enter the
quantity query interface. You can view power statistics on this screen.
6.11 Set Parallel Operation Mode
The IT8200 series electronic load supports multiple instruments to work in
parallel mode to provide more power and current output capability. Under the
parallel mode, All features are set up from the master unit.
This chapter takes three instruments (with operation panel) as an example to
describe how to parallelize the single units and how to return from parallel mode
to single mode.
Connect the instruments
⚫ Before connecting the system bus, you must ensure that each instrument is
in single mode (Single).
⚫ Fiber optic cables cannot be flexed or folded. When the cable is too long
and needs to be arranged, gently wrap the cable in a circle and gently tie it.
⚫ Before connecting the cables, ensure that the instrument power switch is off
and the main switch of the AC power input (distribution box) is off.
⚫ Before connecting 3 single instruments to the AC distribution box, ensure
that the distribution box capacity is sufficient. Refer to the corresponding
specifications for the AC input parameters of a single instrument.
For 3U models, the same model can be connected in parallel. Taking three 3U
single instruments (with operation panel) as an example, the steps for parallel
operation are as follows.
