    WARNING - THE 4700 MEASURES VOLTAGES WHICH MAY BE LETHAL; UNSAFE OPERATION MAY RESULT IN SEVERE INJURY OR DEATH. WARNING - IF THE 4700 IS USED IN A MANNER NOT SPECIFIED BY VITREK, THE PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED AND SAFETY MAY BE COMPROMISED.

  • Page 12: Section 3 -Installation, Storage And Shipping

    Mains Measurement Measurement Category I THE 4700 SHOULD NOT BE USED IN AN ENVIRONMENT WHERE CONDUCTIVE POLLUTION CAN OCCUR, E.G. IN AN OUTDOOR ENVIRONMENT. IF FLUIDS OR OTHER CONDUCTIVE MATERIALS ARE ALLOWED TO ENTER THE UNIT ENCLOSURE, EVEN IF NOT POWERED, THEN THE UNIT SHOULD BE IMMEDIATELY TAKEN OUT OF OPERATION AND SERVICED AS SAFETY MAY HAVE BEEN COMPROMISED.

  • Page 13: Shipping And Storage

    The 4700 has a rear panel accessible switch (labeled SHIP) which totally disables the 4700 during shipment if this switch is placed in the down position. If a 4700 with option BP-47 is to be shipped or is to be stored for periods of longer than several days then placing this switch in the down position will prevent the 4700 from being accidently turned on in transit and will also reduce the self-discharge rate of the battery.

    SHIP SWITCH This switch totally disables the 4700 during shipment if it is in the down position. If a 4700 with option BP-47 is to be shipped or is to be stored for periods of longer than several days then placing it in the down position will prevent the 4700 from being accidently turned on in transit and will also reduce the self-discharge rate of the battery.

     The 4700 probes are high impedance probes, as with any such probe they will pick up fields present in the area of the probe yielding a non-zero AC indication when no apparent input is applied. Such fields are always present unless the 4700 is being used in a very sparsely populated area with no local mains supply, or in a shielded environment.

    DC subtracted signal. The starting and ending zero crossings are automatically selected in the 4700 to be approximately one measurement time apart, independently of the amplitude results measurement time. The frequency measurement is used to “lock” the measurement time to an integer number of cycles of the applied signal, so fully synchronous DC and AC measurements are made.

  • Page 30: Band Button

    For measurements of DC and mains frequencies (or higher) the 30-600Hz setting is recommended. The BAND selection has a large effect on the measurement time and on the amount of time the 4700 takes to “lock-on” to a signal when initially applied or changed; see MEASUREMENT TIME in SPECIFICATIONS for details.

    PRINT – READY. This indicates that a suitable printer is properly attached to the 4700 USB printer port and that it is ready to print. Pressing this button causes the 4700 to print a short page containing the present measurement results and a listing of the measurement configuration.

  • Page 32: Result Button

    4700 Operating Manual - May 28, 2015 The 4700 can collect DC and AC measurement results over a user configurable time span. Starting data collection can be performed either manually or automatically. The measurement results are configured on the Primary Measurement Results Screen.

    The screen backlight has a typical life of several thousand hours; this can be extended by turning off the backlight when the 4700 screen is left inactive for a period of time. Also, if option BP- 47 is fitted this can save power during periods of inactivity.

  • Page 37: Maintaining The 4700 Batteries (Option Bp-47)

    The batteries can be degraded if the 4700 is left in storage for long periods of time. If it is planned to take the 4700 out of service for periods of more than a few days, or if the 4700 is to be shipped, then it is recommended to place the rear panel accessible SHIP switch in the DOWN position to prevent degradation of the batteries and also prevent the possibility of the 4700 being accidently turned on.

    CONTROLLING THE 4700 BY THE GPIB INTERFACE CONNECTIONS Using a standard GPIB cable connect the GPIB port on the 4700 rear panel to the GPIB port of a computer. It is recommended to use a high quality, shielded GPIB cable. Cables may be purchased from ViTREK.

    <NR3>. This is a string of characters defining a floating point numeric value, optionally having a polarity, and/or a decimal point, and/or an exponent.

    4700 has become off-line and restart the session. If a session is inactive for more than 1 minute then the 4700 will allow a session to be initiated from a different source, automatically closing the inactive session if a new session is started. This prevents a potential lockup if the user does not close an active session properly.
