Step 4: Select measurement function and range
1. Put the Model 2602A/2612A/2636A in the single-channel display mode with the DISPLAY
key, then select the current measurement function by pressing MEAS or MODE.
2. Select the measurement range with the RANGE keys. For the purposes of this example,
press AUTO RANGE, and note that the AUTO indicator is displayed. 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.
Step 5: Turn output on
Turn the output on by pressing the appropriate OUTPUT ON/OFF key. The
ON/OFF indicator LED will turn on when the channel output is on.
NOTE The Models 2611A, 2612A, 2635A, and 2636A 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 1-5. See
to the Series 2600A Reference Manual for more information.
Step 6: Make measurements
1. 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
2. Use the DISPLAY key to cycle through the various display modes shown in Figure 1-6 (the
User State display messages are defined with specific display commands; see the Series
2600A Reference Manual for more information).
3. Press the MEAS key several times to display measured voltage, resistance, and power.
Typical values for the 10kΩ resistor are: 10.0000V, 10.0000kΩ, and 10.0000mW.
Step 7: Turn output off
When finished making measurements, turn the output off by pressing the OUTPUT ON/OFF key.
The OUTPUT indicator light will turn off.
