Elditest warrants its probes for normal use and operation within specification for a
period of one (1) year from the date of shipment (accessories and manual not in-
cluded).
In exercising its warranty, Elditest, at its option, will either repair or replace any as-
sembly returned within the warranty period. owever, this will be done only if the
product is determined by Elditest’s examination to be defective because of work-
manship or materials, and the defect is not caused by misuse, neglect, accident,
abnormal conditions of operation, or damaged by attempted repair or modifica-
tions by non-authorized facility.
The customer will be responsible for the transportation and insurance charges for
the return of products.
This warranty replaces all other warranties, expressed or implied, including, but
not limited to, any implied warranty of merchantability, fitness, or adequacy for any
particular purpose or use. Elditest shall not be liable for any special, incidental or
consequential damages, whether in contract or otherwise.
Warranty
This electronic product is subject to disposal and recycling regulations
that vary by country and region. Many countries prohibit the disposal
of waste electronics equipment in standard waste receptacles.

ELDITEST
To avoid personal injury and to prevent fire or damage to the probe or any product
connected to it, review and comply with the following safety precautions.
Use of this probe or test instrument it is connected to in a manner not specified by
the manufacturers may impair protection mechanisms.
Connect to properly grounded instruments. Use only with test instruments having
their BNC input connected to earth ground. Do not connect the probe ground ter-
minal to any point which is at a potential other than earth ground.
Do not disconnect the probe from instrument during measurement. Connect the
probe to the measurement instrument before connecting the probe to the test cir-
cuit.
Do not apply to the input any potential that exceeds the maximum rating of the
probe.
Comply with the voltage derating curve. When measuring higher frequency sig-
nals, be sure to comply with the Voltage vs Frequency Derating Curve.
Do not remove probe casing. Removal of the probe’s casing may expose you to
electric shock.
Do not use if any part is damaged. All maintenance should be referred to a quali-
fied service personnel only.
Do not use in wet or explosive atmospheres.
For indoor use only.

Basic Operation
The GE4500 Series are passive high impedance voltage oscilloscope probes de-
signed and calibrated for use with general purpose oscilloscopes having an input
impedance of 1 MΩ shunted by 13 pF, however selected models may be compen-
sated for use with instruments having an input capacitance between 10 to 30 pF.
Models with RA suffix are compatible with readout function oscilloscopes that au-
tomatically detect probe attenuation and adjust their readout scale accordingly.
Probe Compensation
Proper compensation of the probe is required to assure amplitude accuracy of the
waveform being measured by matching the probe to the oscilloscope’s input ca-
pacitance. Compensation should be adjusted whenever the probe is connected to
or transferred between oscilloscopes.
Low Frequency (LF):
• Apply a 1 k z square wave to the probe or connect to the oscilloscope’s
calibrator output.
• Adjust the trimmer located on the BNC Box (LF) for a flat topped square wave
per center illustration.
Procedure:
Incorrect Correct Incorrect
WARNING.To avoid electric shock, keep fingers behind the probe’s finger guard
during use.
igh frequency ( F):
(Should seldom require adjustment, however, if adjustment is required)
• Apply a 1 M z square wave to the probe (<0.7 ns rise-time).
• Adjust trimmers located on the BNC box ( F) for a flat topped square wave per
center illustration.

Definitions:
Measurement Category I (CAT I) is for measurements performed on circuits not directly connected to mains.
Measurement Category II (CAT II) is for measurements performed on circuits directly connected to the low voltage in-
stallation. Examples are on household appliances, portable tools and similar equipment.
Pollution Degree 2 refers to an operation environment where normally only dry non-conductive pollution occurs
Temporary conductivity caused by condensation must be expected.

Use the following guidelines:
• Clean only the exterior of the probe, cables and accessories. Use a soft cotton
cloth moistened with a mild detergent and water solution. Do not allow any
portion of the probe to be submerged at any time.
• Dry the probe and accessory thoroughly before attempting to make any voltage
measurement.
• Do not subject the probe to solvents or solvent fumes as these can cause deteri-
oration of the probe body, cables and accessories.
