3.2.7.6. OPP test. This allows the parameters of the over power protection test to
Be Set up. Each press of the OPP button moves the setting function. The
Sequence of the OPP test along with the setting value is as follows:
 OPP Press Start (pressing the red START/STOP button starts the test)
 PSTAR (power start point) lower display provides setting in watts “W”
 PSTEP (power steps) lower display provides setting in watts “W”
 PSTOP (power stop point) lower display provides setting in watts “W”
 VTH (voltage threshold) lower display provides setting in volts “V”
When the test is started the lower display will show the power value
Being taken by the load. If the Device Under Test is able to supply the
Load according to the values set then the middle display will show PASS
And the lower display will show the maximum power taken during the
OPP test. If, during the test, OTP is displayed the over temperature
Protection has been engaged. Similarly if OPP is shown on the display
The over power protection has been activated.
3.2.7.7. OCP test. This allows the parameters of the over current protection test
To be set up. Each press of the OCP button moves the setting function.
The sequence of the OCP test along with the setting value is as follows:
 OCP Press Start (pressing the red START/STOP button starts the test)
 ISTAR (current start point) lower display provides setting in amps “A”
 ISTEP (current steps) lower display provides setting in amps “A”
 ISTOP (current stop point) lower display provides setting in amps “A”
 VTH (voltage threshold) lower display provides setting in volts “V”
When the test is started the lower display will show the current value being
Taken by the load. If the Device Under Test is able to supply the load
According to the values set then the middle display will show PASS and the
Lower display will show the maximum current taken during the OCP test. If,
During the test, OTP is displayed the over temperature protection has been
Engaged. Similarly if OPP is shown on the display the over power protection
Has been activated.
3.2.8. and CC, CR, CV, CP Indicator
There are four operating modes. These can be selected in turn by pressing the
"MODE" key on the 3310F series Electronic Load module. The sequence is:
 (CC) Constant Current
 (CR) Constant Resistance
 (CV) Constant Voltage
 (CP) Constant Power
The appropriate LCD will illuminate according to the operating mode is selected.
