For bench-top use, choose a clear, uncluttered area. Ensure that there is at least 2" of clearance at the exhaust vents on the
side panels. Pull-down feet are located on the bottom of the instrument. Rack mounting instructions are provided with the
optional rack mount kit.
2.2 Power Requirements
The 4240 Series is equipped with a switching power supply that provides automatic operation from a 90 to 260 volt, 47 to 63
Hz, single-phase, AC power source. Maximum power consumption is 15W and 25VA. For metric fuse sizes, use the metric
fuse kit supplied. Connect the power cord supplied with the instrument to the power receptacle on the rear panel. See Figure
3-2.
Caution Before connecting the instrument to the power source, make certain that a 0.5-ampere time delay fuse (type
T) is installed in the fuse holder on the rear panel.
Before removing the instrument cover for any reason, position the input module power switch to off (0 =
OFF; 1 = ON) and disconnect the power cord.
2.3 Connections
Sensor(s)
Connect the sensor that covers the frequency range of the measurement to the CHANNEL 1 sensor
connector on the front (Standard) or rear (Optional) panel, as follows. Connect the sensor to the sensor
cable. Connect the sensor cable to the CHANNEL 1 Input, holding the red mark on the cable connector up.
For two-channel measurements, use the same procedures to connect the second sensor to the CHANNEL 2
Input.
Note
If the sensor connector is not a type N, install the appropriate adapter (from the accessories kit) on the
calibrator output connector.
