WARNING The maximum voltage between any terminals to chassis ground is 350V
peak. Exceeding this value may cause a breakdown in insulation, creating
a shock hazard.
CAUTION The maximum voltage between CHANNEL 1 HI and LO is 120V. The
maximum voltage between CHANNEL 2 HI and LO is 12V. Exceeding
these voltage values may result in instrument damage.
Verification procedures
Voltage measurement accuracy
Follow the steps below to verify that Model 2182 voltage measurement accuracy is within
specified limits. The test involves applying precise DC voltages and then verifying that the
Model 2182 voltage readings are within required limits.
100mV – 100V range accuracy
1. With the power off, connect the DC calibrator to CHANNEL 1 of the Model 2182 input
jack, as shown in Figure 1-1. Connections for the Model 2107 Low Thermal Input Cable
are summarized in Table 1-2.
