Step 3: Connect BE1-11m Terminals C17 (polarity) and C18 to a 180 Hz (third harmonic) ac voltage

source.

Step 4: Apply the voltage values listed in Table 99 and verify voltage-measuring accuracy by using the

Metering Explorer in BESTCOMSPlus to open the Analog Metering, Voltage, Secondary
Voltage screen. The Metering > Analog Metering > Voltage > Secondary Voltage screen of the
front-panel display can also be monitored to verify voltage measurements. Accuracy is

±0.5%.

Frequency Verification

Step 1: Connect BE1-11m Terminals C13 (polarity) and C16 (A to Neutral of the three-phase voltage

input) to a 60 hertz ac voltage source (line voltage).

Step 2: Connect BE1-11m Terminals C17 (polarity) and C18 (Auxiliary Voltage Input) to a second 60-

hertz ac voltage source (bus voltage).

Step 3: Apply 115 volts at 0 degrees and 60 hertz to both sources. Verify the measuring accuracy of the

line and bus frequency by using the Metering Explorer in BESTCOMSPlus to open the Analog
Metering, Frequency screen. The Metering > Analog Metering > Frequency screen of the front-
panel display can also be monitored to verify frequency measurements.
