1 Introduction About This Manual About This Manual The descriptions and instructions in this manual apply to the Agilent U1731C, U1732C, and U1733C handheld LCR meters (hereafter referred to as the LCR meter). The model U1733C appears in all illustrations. Documentation map The following manuals and software are available for your LCR meter. For the very latest version, please visit our website at: http://www.agilent.com/find/hhTechLib. Check the manual revision on the first page of each manual.
Introduction Preparing Your LCR Meter 1 Preparing Your LCR Meter Check the shipment When you receive your LCR meter, check the shipment according to the following procedure. 1 Inspect the shipping container for damage. Signs of damage may include a dented or torn shipping container or cushioning material that indicates signs of unusual stress or compacting. Save the packaging material in case the LCR meter needs to be returned.
1 Introduction Preparing Your LCR Meter 1 Open the battery cover. Lift the tilt stand. Loosen the screw with a suitable Phillips screwdriver and remove the battery cover as shown in Figure 1- 1. 2 Insert the battery. Observe the proper battery polarity. The terminal ends of the battery are indicated inside the battery compartment. 3 Close the battery cover. Place the battery cover back in its original position and tighten the screw.
Introduction Preparing Your LCR Meter CAUTION 1 To avoid instruments being damage from battery leakage: • Always remove dead batteries immediately. • Always remove the battery and store it separately if the LCR meter is not going to be used for a long period. Table 1-1 Battery level indicator Indication Battery capacity Full capacity 2/3 capacity 1/3 capacity (Flashing periodically) Almost empty (less than one day)[1] [1] Battery change advised.
1 Introduction Preparing Your LCR Meter To power OFF your LCR meter, press the power- on button again. NOTE You can change the power-on behavior of your LCR meter for subsequent power cycles. See “Changing the initial power-on behavior” on page 56 for more information on changing the LCR meter’s power-on setting. Automatic Power-Off (APO) Your LCR meter automatically turns off after 5 minutes (default) if no keys are pressed.
Introduction Preparing Your LCR Meter 1 Selecting the range Range Auto Pressing switches the LCR meter between manual and autoranging. It also cycles through the available LCR meter ranges when manual ranging is enabled. Autoranging is convenient because the LCR meter automatically selects an appropriate range for sensing and displaying each measurement. However, manual ranging results in better performance, since the LCR meter does not have to determine which range to use for each measurement.
1 Introduction Preparing Your LCR Meter Adjusting the tilt stand To adjust the LCR meter to a 60° standing position, pull the tilt- stand outward to its maximum reach.
Introduction Preparing Your LCR Meter 1 Connecting the IR-USB cable You can use the IR communication link (IR communication port, located at the rear panel) and the Agilent GUI Data Logger software to control your LCR meter remotely. Hence, you can only perform data logging operations in the Agilent GUI Data Logger application with the LCR meter connected via the USB- IR cable to the PC.
1 Introduction Preparing Your LCR Meter Power-on options Some options can be selected only while you turn the LCR meter on. These power- on options are listed in the table below. To select a power- on option, press and hold the specified key in Table 1- 2 while turning the LCR meter ON ( ). Table 1-2 Power-on options Key Description Tests the LCD. Hold Rec Range Auto All annunciators are displayed in the LCD. Press any key to exit this mode. Simulates the Auto Power-Off (APO) mode.
