Calibrating the Generator
5-36 Force FX-8C Service Manual
c. Stop activation. If the output current reading was too high, lower
the Z factor. If the reading was too low, raise the Z factor.
To change the Z factor by ones, press the Coag up (∆) or down
(∇) arrow buttons. To change it by hundreds, press the Cut up (∆)
or down (∇) arrow buttons.
Repeat this step until the voltmeter reading is within the stated range.
The Z factor for the Low cut mode is adjusted automatically.
3. Adjust the Z factor for the Blend mode.
a. Press the Blend button.
b. Press the footswitch cut pedal and check the voltmeter for a
reading equivalent to 1000 ± 10 mA rms.
c. Stop activation. If the output current reading was too high, lower
the Z factor. If the reading was too low, raise the Z factor.
To change the Z factor by ones, press the Coag up (∆) or down
(∇) arrow buttons. To change it by hundreds, press the Cut up (∆)
or down (∇) arrow buttons.
Repeat this step until the voltmeter reading is within the stated range.
4. Disconnect the test cables and remove 200 ohm resistor.
5. To save the reactance gain calibration and go to the next calibration
step, press the Bipolar up arrow (∆) button.
Next, go to Step 8 – Check and Adjust the ECON Factor.
Step 8 – Check and Adjust the ECON Factor
Equipment required:
• Two short test cables (less than 61 cm [24 in.] long) with banana plugs
• 30, 100, and 500 ohm noninductive power resistors (such as the Dale
NH-250)
• Bipolar footswitch and monopolar footswitch
• Current transformer (such as the Pearson Model 411 or equivalent)
• True RMS voltmeter (such as the Fluke 8920 or equivalent).
Verify that the Bipolar display shows calibration step 8.
