Model CL-100 Bipolar Temperature Controller - Harvard Apparatus UK

12Operation (Cont’d)Warner Instruments Bipolar Temperature Controller Model CL-100Manual ModeIn manual mode,the MANUAL VOLTAGE control (Item K) is used to set theoutput voltage to a fixed value. In manual mode, the SET TEMPERATUREcontrol (Item H) is disabled, as is the feedback system of the CL-100.Operation is again straightforward. Set the CL-100 to accept internalcommands by setting the INTERNAL/EXTERNAL SELECT control (Item J) tointernal. Place the CL-100 into manual mode by switching the COOLINGMODE SWITCH (Item C) to manual. Switch the METER (Item B) to OutputVolts and adjust to the desired set-point using the MANUAL VOLTAGEcontrol (Item K).Alternatively, the CL-100 can be commanded using external inputs. Set theCL-100 to external commands by setting the INTERNAL/EXTERNALSELECT control (Item J) to external. In this mode the CL-100 will acceptexternal voltage commands at the EXT VOLT SET BNC (Item P) located onthe instrument rear panel.In this mode, the instrument operates as a 0-12 VDC power supply that canprovide up to 1.5 A of current to a device. Use this mode with heatersystems that will operate properly with a fixed voltage and lack feedbackthermistors.Publication 5702-001-REV-Awww.warneronline.com
