Low-thermal Input Cables with Spade Lugs

Description

The Model 2107 Low-Thermal Input Cables with Spade Lugs are input cable assemblies for the Model 2182
Nanovoltmeter. The assemblies are terminated with a two-channel LEMO connector on one end and four
copper spade lugs on the other.

For details on making connections to a test device, refer to the 2182 Nanovoltmeter User's Manual.

Input terminal cleaning

Before connecting the input cable to the 2182, clean the copper contacts of the LEMO connectors using DeoxIT
D100L deoxidizing solution.

Clean the input terminals whenever the cable is disconnected from the Model 2182 for an extended
period of time. A bottle of DeoxIT is supplied with the Model 2182.

1. Turn off the 2182.

2. Disconnect the power cord and any other cables or wires connected to the instrument.

3. Stand the 2182 on end so that the front panel is facing up.

4. Apply one drop of DeoxIT to each of the four contacts of the LEMO input connector on the 2182. You can
use a clean wire (such as a resistor lead) to carry a drop of the solution from the bottle of DeoxIT to the
connector.

5. Wipe off any excess DeoxIT using a clean cloth.

6. Connect and disconnect the cable from the Model 2182 several times to spread the DeoxIT solution and to
clean the input cable contacts.

Warnings

Do not exceed the maximum signal levels of the accessory or the attached instruments, as
defined in the specifications and operating information.

Probe tips should only be used by qualified personnel who recognize shock hazards and are
familiar with the safety precautions required to avoid possible injury. Inspect the probe tips,
lead insulation, and insulating sheaths for wear, cracks, or breaks before each use. To
prevent voltages from being exposed or connections from shorting together, make sure the
probe tips and test leads are properly connected before applying power.

Never touch or change the connections when power is applied to the circuit under test.
Always turn off test system power and discharge all capacitors before connecting or
disconnecting the probe tips.

Failure to adhere to these guidelines can result in personal injury or death due to electric
shock.
