SAFETY SUMMARY
Only trained operators shall use the IRM-5000P. All devices under test shall be off line
and fully isolated.
DO NOT SERVICE OR TEST ALONE
Do not perform test procedures or service unless another person is also present who is
capable of rendering aid and resuscitation.
DO NOT MODIFY TEST EQUIPMENT
Due to the added risk of introducing additional or unknown hazards, do not install
substitute parts or perform any unauthorized modification to the IRM-5000P. To ensure
that all designed safety features are maintained, it is recommended that all repairs be
performed only by Vanguard Instruments Company’s factory personnel or by an
authorized repair service center. Unauthorized modifications can cause serious safety
hazards and will nullify the manufacturer's warranty.
IRM-5000P CARE AND TEST PRECAUTIONS
The area around the IRM-5000P’s charging circuits and test terminals must be kept
clean and dry to prevent high-voltage leakage paths, which can cause hazardous
conditions or erroneous measurements. Failure to heed these precautions may result in
unsafe operating conditions, cause erroneous test results and will void the Vanguard
Instruments Company’s warranty.
WARRANTY
The IRM-5000P’s warranty is valid only to the original purchaser. The IRM-5000P is
guaranteed to be free from defects in material and workmanship for a period of only one
year. The warranty does not apply to normal wear or damage due to misuse, abuse,
improper storage, improper installation, accident, unauthorized repairs or alterations.

1.0 FUNCTIONAL DESCRIPTION
Vanguard Instruments Company’s model IRM-5000P mega-ohmmeter is a
microprocessor-based, high-voltage, insulation test meter. The IRM-5000P is rugged
and portable, making it ideal for use in electrical, utility substations and in many other
industrial applications.
The sophisticated, insulation tester uses a dual-microprocessor design. One processor
is dedicated to the control of the power supply and measuring circuitry. While, the
second microprocessor is dedicated to the display, printer control and user interfaces.
These microprocessors interface with each other via an optical link to ensure the
operator’s safety and isolation from the high-voltage inside the unit.
1.1 Test Voltage
The IRM-5000P can run tests with pre-set voltages consisting of: 500, 1000, 2500, and
5000 Vdc. The unit can also output test voltages specified by the user ranging from
50 Vdc to 5000 Vdc with a resolution of ±1 Vdc step.
1.2 High-Voltage Warning Display and Audible Alarm
A warning LED indicates when high-voltage is present at the test terminals. An audible
alarm will also alert the operator that a test is in progress.
1.3 Capacitor Discharge
The IRM-5000P automatically discharges any test charge left on the test material after
each test. The High-Voltage LED will warn the operator of the potential hazard that
exists during each discharging period.
1.4 Voltmeter
The IRM-5000P will always display on the LCD screen the voltage at the test terminals.
Thus, the user can use the IRM-5000P as a voltmeter. Measurable voltage input
ranges from 50 to 1250 Volts, ac or dc.
1.5 Keypad
An alphanumeric keypad allows users to enter test identification numbers and control
functions.
1.6 LCD Display
A back-lit, 4-line by 20-character, LCD screen outputs test data and user messages. To
conserve energy, the backlight of the LCD will power off after 45 seconds of inactivity.
Pressing any button on the keypad can restore the backlight. The adjustment to the
contrast of the LCD can be done from the keypad. Pressing the “↑” key for more than 3
seconds will darken the LCD screen. Pressing the “↓” key for more than 3 seconds will
lighten the LCD screen.

MODEL IRM-5000P USER’S MANUAL

1.7 Built-in Thermal Printer
A built-in, thermal printer will output test results on 2½-inch-wide, thermally sensitive
paper. Test results can be printed in both tabular and graphic formats. Moving the
paper inside in the printer can be done from the keypad. Pressing and immediately
releasing the “↑” key will advance the printer paper. While, pressing and immediately
releasing the “↓” key will retract the printer paper.
1.8 Test-Report Storage Capability
The IRM-5000P uses Flash Electrically Erasable PROMS (EEPROM) to store test
reports in the memory. Stored test results can be recalled later by the user to be
reanalyzed, print test reports or to transfer data to an IBM-compatible, personal
computer for record keeping. Up to 90 test reports can be stored in the EEPROMs.
1.9 Computer Interface
An RS-232C port can be used to interface with an IBM-compatible computer. A
Windows-based Insulation-Resistance Analysis program allows users to retrieve test
reports stored in the IRM-5000P. Thus, the user can generate test reports with an office
computer. A special feature of the software will also allow the user to overlay several
resistance curves on a color monitor. The user is then able to monitor the resistance
deterioration of a test material over time.
An RS-232C cable is also furnished with every unit. The IRM-5000P requires a 9-pin,
D-type, male-to-female connector. The RS-232C port connector pin assignment is
shown in Table 1.0 below:

PIN SIGNAL
2Tx Data
3Rx Data
5Gnd
1.10 Temperature Probe
A non-contacting, infrared, temperature probe is also provided with each IRM-5000P.
Recording the temperature of the device under test (DUT) permits the IRM-5000P to
convert the recorded resistance to the equivalent resistance reading at 20 °C and 40°C.
The feature provides the user the ability to compare the resistance reading of the DUT
regardless of the temperature at which the reading was taken.
1.11 Power Source
The IRM-5000P can operate from internally, sealed, rechargeable, lead-acid batteries or
it can be operated from an external power source. The lead-acid batteries provide up to
five hours of continuous operation. An isolated transformer allows the IRM-5000P to be
used while the batteries are charging. The factory or an authorized user can set the
desirable power sources to be: 110/220 Vac, 50/60 Hz or 220/440 Vac, 50/60 Hz
according to Table 2.0.

1.10 Test Terminals
The IRM-5000P has three test terminals: POS, NEG, and GUARD. For measurements
up to 100 Giga-ohms, the user can make measurements using the POS and NEG
terminals. For higher resistance readings, the user may want to use the GUARD
terminal to remove any surface-leakage current affecting the measurement. For an
additional explanation about the GUARD terminal, please refer to Appendix C.

4.0 TEST MODE SUMMARY
4.1 Insulation Resistance ( R ) Test
The Insulation Resistance test measures the insulation resistance at selected test
voltages to provide an instantaneous resistance reading.
4.2 Polarization Index (PI) Test
The Polarization Index test measures the ratio of insulation resistance after one minute
and then after ten minutes. The Polarity Index is derived from a ratio of the two periods,
where the resistance value at ten minutes is divided by the resistance value at one
minute. See Appendix A for more details.
4.3 Step Voltage (SV) Test
The Step Voltage test is based on an ideal insulator producing the same resistance
measurement at all voltages. As an example, an insulator that is over stressed will
measure lower resistance values at the higher voltages. Accordingly, the resistances
measured on an over-stressed insulator at increasingly higher voltages (steps) will
produce decreasingly lower resistance values. A typical Step Voltage test duration is
five minutes. The IRM-5000P will sequentially take resistance readings of the DUT at
one-fifth increments of the final test voltage at one minute intervals. Default test
voltages are selectable at 2,500 Vdc or 5,000 Vdc. The user can also select a specific
voltage and intervals.
4.4 Dielectric Discharge (DD) Test
The Dielectric Discharge test measures the dielectric absorption of the tested material.
The default test requires 30 minutes of applying full voltage followed by a one minute
discharging of the DUT. The DD value is then calculated from the formula:
