Step 5: Turn output on
Turn the output on by pressing the appropriate OUTPUT ON/OFF key. The
ON/OFF indicator LED will light when the channel output is on.
NOTE
Step 6: Make measurements
1.
Put the Model 2602/2612 in the single-channel display mode with the
DISPLAY key.
Press the LIMIT key, then press ENTER or the Rotary Knob.
Move the cursor to the 10s digit, then press the Rotary Knob to enter the
EDIT mode.
Using the numeric keys or the Rotary Knob, set the limit value to
10.000mA, then press ENTER or the Rotary Knob.
Put the Model 2602/2612 in the single-channel display mode with the
DISPLAY key, then select the current measurement function by pressing
MEAS or MODE.
Select the measurement range with the RANGE keys. For the purposes of
this example, press AUTO RANGE, and note the AUTO annunciator turns
on. The instrument will automatically select the best range based on the
measured value. You can also use manual ranging by pressing the up or
down RANGE key, but be sure to use the lowest possible range for best
accuracy.
The Models 2611 and 2612 are equipped with a safety
interlock circuit that prevents operation on the 200V range
if the circuit is not energized. This circuit is illustrated in
Figure 1-4. Refer to Section 10 of the Series 2600 Reference
manual for more information.
Observe the readings on the display (Press TRIG if necessary to trigger the
unit to begin taking readings.). For the single-channel display mode, the
readings will appear on the top line, while source and limit values are on the
bottom line. For the 10kΩ resistor under test, typical display values are:
1.00000mA
SrcA: +10.0000 V LimA:010.0000mA
