Awesome, glad to hear that man. Have you replaced the banana aligator cable with a more solid and quality one though? |
| torch:
Replaced? Not exactly. I have a couple of alternate leads that I use for certain applications, but the originals are still in use when appropriate. They have held up better than I thought they would originally. |

Finally got mine - KA3305P Very heavy and the fans are now quite. No complaints so far. |

Hi all, sorry for up. Do someone know if the serial setting of channel 1 and channel 2 can be used for dual supplies? Channel 1 positive would be +V, channel 2 negative would be -V and channel 1 negative with channel 2 positive would be the 0V reference and should be connected to the green earth. Thanks in advance. |

In serial mode, yes Channel 1 + is most positive, Channel 2 - is most negative and Ch 1 is bonded internally to Ch 2, but floating above mains earth. You can connect either Ch 1- or Ch 2 + to a green terminal to make that reference to mains earth. In this mode, the Ch 2 controls set the voltage and current limits for both channels equally, Ch 1 controls have no effect. So to power, for example, an op amp, Ch1 + would be your positive rail, Ch1 - would be your ground plane and Ch2 - would be your negative rail. Both rails would be equal but opposite, controlled by Ch2 settings. Note that changing the settings in serial (or parallel) mode also changes the memory setting for Ch1 to the Ch2 settings. |
