Page 29: Getting Started
Gettingstarted Usersettingsscreen 5 Getting started 5.1 Powering on the Super-Thermometer CAUTION: Before powering the Super-Thermometer on, ensure that the line voltage selection is set properly. Refer to Section 3.3, Line voltage and fuses, on page 11 for instructions. Power the Super-Thermometer on by setting the power switch located on the back panel to the On position. After power is on, pressing the Power Standby switch on the front panel puts the system into hibernation, leav- ing key components such as the resistor oven powered on. -

START-UP HELP- determines whether the User Settings screen appears automatically after power-on. When the settings is ON the User Settings screen will appear every time the power is switched on. If the setting is OFF the Measurement screen will appear instead. - Page 31 Gettingstarted Connectingaprobeorresistor The DWF connectors are labeled with C1, C2 (current connections) and P1, P2 (measurement potential con- nections). The guard connector is labeled with a “G” and is used for connecting to a probe or resistor guard or shield. The guard connection may help reduce measurement noise. Connect a probe or resistor, as specified by the device’s manufacturer, to any one of the four measurement channels located on the front panel.
