4700 Operating Manual - May 28, 2015
SECTION 1 – PRODUCT INFORMATION
FEATUR ES
The 4700 is an advanced Precision High Voltage Meter with many standard features which make it unique in this field.
The 4700 can measure from 0.01V to 140KV (10KV without optional accessory probe). Accuracies down
to 300ppm and resolutions down to 10ppm can be achieved.
There’s no worry about selecting the incorrect operating range or mode, the 4700 always automatically
measures both the DC and AC signal contents and displays them both, along with the frequency and crest factor of applied AC voltages. The 4700 is effectively a single range instrument, using non-linear DSP technology to achieve a very wide dynamic range. For most applications the user never has to use any of the 4700 controls.
The 4700 is capable of measuring very low frequency AC signals down to 0.009Hz. You can now test the
accuracy of your VLF type dielectric tester with confidence.
The 4700 has a ripple measurement mode, allowing it to accurately reject the DC signal content and only
measure the AC ripple. You can now test the ripple on high voltage DC power supplies.
The 4700 makes differential measurements. Common mode offsets up to 800Vpk are accommodated
using the COMMON terminal; this can be extended up to 100KV by using external available accessory probes.
The 4700 has a selectable high-speed mode allowing dielectric tester ramp and dwell times and ramp
conformance to be plotted and printed as a graphics chart.
The 4700 can be used as a data logger, graphically charting the measurements over periods from a second
to several days. The chart can be printed at any time.
The present measurements can be printed on a suitable USB printer, allowing the user to make a paper
record of the measurements.
If the user wishes to use the 4700 with a computer, then RS232 or Ethernet or available GPIB interfacing
can be chosen as the interfacing medium between them.
AVAILABLE OPTIONS AND ACCE SOR IES
INT ERFA C ING OPTI ONS

SECTION 2 – SAFETY
The user must be aware of these safety warnings at all times while using the 4700.
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.
GROUNDING
WARNING - THE USER MUST SECURELY GROUND THE PROTECTIVE GROUND TERMINAL LOCATED ON
THE 4700 REAR PANEL WHEN IN USE OR WHENEVER HIGH VOLTAGES MAY BE PRESENT.
NEVER – ATTEMPT TO USE THE 4700 WITHOUT THE PROTECTIVE GROUND TERMINAL BEING GROUNDED IN AN ATTEMPT TO INCREASE THE COMMON MODE VOLTAGE CAPABILITY OF THE 4700. THIS IS EXTREMELY DANGEROUS AND CAN DAMAGE THE 4700.
TER MINALS AND WIRING
WARNING - THE 4700 MEASURES VOLTAGES OF UP TO 10kVrms ON THE DIRECT TERMINAL, AND
VOLTAGES UP TO 140KVrms ON A PROBE TIP TERMINAL, THESE VOLTAGES CAN CAUSE SEVERE INJURIES OR DEATH. THE USER MUST ENSURE THAT CONNECTIONS TO THESE HAVE SUFFICIENT INSULATION FOR THESE VOLTAGES. EVEN WHEN SUFFICIENT INSULATION IS PRESENT, THE USER SHOULD NOT PUT ANY PART OF THEIR BODY IN PROXIMITY TO THE CONNECTIONS WHILE HIGH VOLTAGES ARE PRESENT (AT LEAST ½ INCH PER KV IS RECOMMENDED). THE USER SHOULD NOT INSERT OR REMOVE ANY CONNECTIONS TO THE 4700 WHEN HIGH VOLTAGES ARE PRESENT.
WARNING – DO NOT APPLY HIGH VOLTAGES TO A PROBE WITHOUT IT BEING PROPERLY PLUGGED INTO A 4700.
WARNING - WHEN USING AN EXTERNAL PROBE OR PROBES WITH THE 4700, NO PART OF THE USERS’ BODY MUST BE WITHIN 4” (HVP-35 OR HVL-35), 8” (HVL-70) OR 12” (HVL-100) OF THE PROBE BODY
(OTHER THAN THE HANDLE OF THE HVP SERIES PROBES) WHEN VOLTAGES MAY BE PRESENT.
WARNING – WHEN AC VOLTAGES ARE PRESENT, EVEN IF THERE IS SUFFICIENT INSULATION ON THE CONNECTIONS, THERE MAY BE SIGNIFICANT CAPACITIVE COUPLING WHICH CAN CAUSE AN UNSAFE CURRENT TO FLOW INTO NEARBY OBJECTS AND ALSO CORONA MAY OCCUR EVEN OUTSIDE OF THE INSULATION. THESE EFFECTS ARE MADE WORSE BY SHARP CORNERS. IN SEVERE CASES CORONA CAN CAUSE INTERFERENCE WITH THE MEASUREMENTS OF THE 4700 AND WILL REDUCE THE CAPABILITIES OF THE WIRING INSULATION OVER TIME, EVENTUALLY RESULTING IN INSULATION FAILURE.

4700 Operating Manual - May 28, 2015
SH IPPI NG AN D STORA GE
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.
INI TIAL IN SPEC TION
After the 4700 has been shipped or otherwise handled in an unknown manner, the user should visually inspect the 4700 for damage before attempting to operate it. Particular attention should be taken to ensure that there are no significant dents or cracks in any outer surfaces, there are no scratches on the front panel LCD touchscreen and that all terminals are securely mounted to the unit. If any significant dents or any loosely mounted terminals are noted then it is recommended that the 4700 be serviced prior to being placed into use, as safety may have been compromised.

4700 Operating Manual - May 28, 2015
SECTION 4 – INPUT SPECIFICATIONS
Throughout this section, a voltage on a single terminal or probe input refers to the voltage between the specified terminal or probe input and the 4700 chassis ground.
The accuracy specifications are valid for a period of 1 year at ambient temperatures within ±5C of calibration temperature (add 0.004% of reading per C outside of this). The accuracy specifications include the measurement uncertainties in the standards and methods employed by Vitrek during calibration of the 4700 and probes; to obtain the accuracy relative to the standards and methods used in the actual calibration of the 4700 or probes reduce all DC accuracy specifications by 0.0075% of reading and all AC accuracy specifications by 0.025% of reading.
The accuracy specifications for probes assume the use of the probe with the specific 4700 used for its’ calibration. When this is not the case, add 0.01% of reading to all probe accuracy specifications.

This is the effect of self-heating induced as a result of voltage on the DIRECT terminal. This effect is not included in the accuracy specifications above, takes up to several minutes to become fully apparent and a similar time to dissipate.

HVP-35 OR H VL-35 HI P ROBE:CO MMO N MEA SURE MENT SP ECIF ICATI ONS
This section contains the specifications for the 4700 when using a single HVP-35 or HVL-35 probe (i.e. the 4700 is measuring the voltage between the HI PROBE tip and COMMON terminal of the 4700). These specifications assume that no signal is present on the DIRECT terminal.
PRO BE L OCATI ON
Full accuracy specifications are valid assuming that there are no objects within a cylinder of radius 18” centered on
the probe body extending from the handle (or base) to a point 6” beyond the probe tip. The connection to the probe tip is assumed to extend from the probe tip in line with the probe for at least 6”.
Typically the effect of a hand-sized grounded object is <0.01% at 60Hz when placed 4” from the probe and <0.1% at 400Hz when placed 18” from the probe. As long as objects do not move relative to the probe, there is negligible effect on DC measurements caused by nearby objects. Objects generating fields may need to be placed further away from the probe than these figures.
