Caution
To prevent damage to the Product, make sure you do not go
above the maximum input voltage or current. See the Maximum
Input Level specifications in Chapter 1.
4. Push the LCOMP ON or OFF as necessary.
Note
When LCOMP is on, Product bandwidth and accuracy are decreased.
5. Push
B
,
C
, or
D
to set the output range. The indicator in the range button
illuminates to show the set range.
Note
Only the 2 amp and 20 amp range can be set to the low-current terminals.
6. Push
H
or
K
to set the output current terminals. The indicator in the button
illuminates to show which terminals will source the output current.
7. Set the voltage source output to a voltage that gets the necessary current out of the
Product. The input voltage range of the Product is 0 volts to 2 volts. To output 15
amps from the Product on the 20-amp range, set the input voltage to 1.5 volts. See the
specifications section in Chapter 1 for input voltage and current limits. When the
input value is more than the limit, the Product sets itself to the standby mode.
8. Connect the output terminals to the load. Make sure the connections are tight.

How to Setup Multiple Amplifiers
When more than 120 amps is necessary, you can use a maximum of 10 Products
connected in parallel.
Greater than 120 Amps Operation
To setup multiple amplifiers for more than 120 amps output:
Connect one end of the control cable to the rear-panel control output connector on one
Product. Connect the other end of the cable to the rear-panel control input connector on a
second Product. See Figure 2-5.
