__________________________________________________________________________OPERATING INSTRUCTIONS
In the series tracking mode, the maximum output voltage of both the “A” and “B” supplies can be simultaneously varied with one control. The maximum “B” supply voltage can be set to the same value of the “A” supply by using the “A” VOLTAGE control.
The output voltage (across the two supplies) is actually double the Volt meter reading. The actual output current would be the value read from the mA meter (since the two supplies are wired in series, current flowing through each supply must be equal).
1.Set the power supplies to the TRACKING SERIES mode by setting the TRACKING/INDEPENDENT switch to the SERIES (left) position.
2.Set the A/B Metering switch to the A (up) position.
3.The “B” VOLTAGE AND CURRENT controls are disabled; turn both to their minimum positions. The maximum current is set using the “A” CURRENT control. Follow the instructions for “Setting Current Limit” (INDEPENDENT USE OF “A” OR “B” SUPPLY section of this manual) using the “A” CURRENT control.
4.Adjust the output voltage to the desired level using the “A” VOLTAGE control (remember that the actual output voltage is double the reading on the Volt meter).
5.Turn off the power supply and the equipment to be powered during
6.Connect the positive polarity of the device being powered to the red (+) terminal of the “A” power supply.
7.Connect the negative polarity of the device being powered to the black
