This product conforms to the safety requirements for CAT II measurement
products.
To ensure safe operation of measurement products, IEC 60664 establishes
safety standards for various electrical environments, categorized as CAT I to
CAT IV, and called overvoltage categories. These are defined as follows.
CAT I Secondary electrical circuits connected to an AC electrical outlet
through a transformer or similar device.
CAT II Primary electrical circuits in equipment connected to an AC
electrical outlet by a power cord (portable tools, household
appliances, etc.)
CAT III Primary electrical circuits of heavy equipment (fixed installations)
connected directly to the distribution panel, and feeders from the
distribution panel to outlets.
CAT IV The circuit from the service drop to the service entrance, and to
the power meter and primary overcurrent protection device
(distribution panel).
Higher-numbered categories correspond to electrical environments with
greater momentary energy, so a measurement product designed for CAT III
environments can endure greater momentary energy than one designed for
CAT II. Using a measurement product in an environment designated with a
higher-numbered category than that for which the product is rated could
result in a severe accident, and must be carefully avoided.
Follow these precautions to ensure safe operation and to obtain the full
benefits of the various functions.
WARNING
CAUTION
Before turning the product on, make sure the source voltage

The power cord is connected according to the following
procedure.
1. Check that the main power switch of the unit is off.
2. Check that the power supply voltage is correct, and
connect the proper end of the power cord to the power
input socket (with voltage selector) at the rear of the unit.
3. Plug the other end of the power cord into the power
supply socket.
Grounding
Use the grounding type (three-wire) power cord supplied.
The unit will be grounded automatically.
The maxim um voltage whic h can be applied to the test terminals of t he
3511-50 unit is 40 V DC. If a DC voltage greater than this is applied
continuously, t he unit m ay be damaged.
For how to apply a DC bias voltage, refer to Section 5.2, " Supplying DC

No test cables are included with the 3511-50 unit. They must be
purchased separately. For details, refer to Chapter 9, "Options."

NOTE
NOTE
Wait for 60 minutes after turning on the power before starting testing, so as
to allow the unit to warm up fully.
How to turn the power off
Turn off the power switch on the rear panel. The test conditions will be
preserved.
Even if the power supply is interrupted because of a power failure or the
like, the test conditions (settings) will not be lost; when the power is turned
on again, the unit will return to its state just before the interruption.
This happens, however, in the normal test mode or comparator execution
mode only.
As shown above, the 3511-50 permits five possible combinations of testing
parameters. Cycle through the combinations by repeatedly pressing.
Use the LED lamps to the left of the measurement display to check on
selected testing parameters.

For details, refer to Section 8.2, "Testing Parameters and Calculation
Equations."
For the 3511-50's test frequency, you may specify either 120 Hz or 1 kHz.
Procedure
Pressto toggle between 120 Hz and 1 kHz. Use the LED lamp to the
left of the key to check on a set test frequency.
3.3Setting the Test Signal Level
For the 3511-50's test signal level, you may specify 1 V, 500 mV or 50 mV.
Procedure
Pressrepeatedly to cycle through available settings: 1 V, 500 mV, and
50 mV. Use the LED lamp to the left of the key to check on a set test
signal level.
Precautions for changing test signal levels
The value of the test signal level may change according to the sample which
is being tested. During measurement, keep in mind that inductance is often
current-dependent.
For testing speed, select from one of the following three levels, depending on
the specific purpose. The slower the testing speed is, the more accurate are
the results.
FAST : Low accuracy testing is performed at high speed.
NORM : The speed used for normal testing
SLOW : High accuracy testing is performed slowly.
Procedure
Pressrepeatedly to cycle through available settings: FAST, NORM, and
SLOW. Use the LED lamp to the left of the key to check on a set testing
speed.

The testing time values above are for reference only, valid when Z-θ is
displayed and varying according to testing parameter setting conditions,
range mode, OPEN/SHORT compensation, and other conditions.
You may set an equivalent circuit mode. Automatic selection is also
possible.
3.5.1Equivalent Circuit Mode
The 3511-50 unit analyses the test sample in terms of a pure inductive
component (L), an equivalent circuit construction composed of a pure
capacitive component (C), and a pure resistive component (R), and
calculates as though these components were connected in series, or
alternatively connected in parallel. Therefore, it is possible for the user to
select either a series equivalent circuit mode or a parallel equivalent circuit
mode for this conceptual connection together of these L, C, and R
components.
When the impedance of the sample being tested is relatively high, the
parallel equivalent circuit mode should be selected manually, and when the
impedance of the sample being tested is relatively low, the series equivalent
circuit mode should be selected manually.
Generally, for a device such as an electrolytic capacitor or the like with a
high D value (i.e., a low Q value), the test values obtained when testing
using series equivalent circuit mode differ from those obtained when testing
using parallel equivalent circuit mode. The greater the resistance component
in the sample being tested, the more this difference in the test values
appears.
For example, the test values for capacitors of the same capacitance which
have different values of D in series equivalent circuit mode and in parallel
equivalent circuit mode may be as follows:
Therefore it is necessary for the user clearly to understand the setting of this
test mode, in order properly to assess test samples.
In general, parallel equivalent circuit mode should be used for elements
which have relatively low capacitance and high impedance such as film
capacitors and ceramic capacitors, since parallel resistance can cause great
loss in this case; while series equivalent circuit mode should be used for
elements which have relatively high capacitance and low impedance such as
electrolytic capacitors, since series resistance can cause great loss in this
case.

If the impedance exceeds the measurement range, the first parameter display
is "UF" (underflow, i.e., impedance below the measurement range) or "OF"
(overflow, i.e., impedance above the measurement range), and the second
parameter display disappears.
To measure a parameter other than Z - i.e., C, L, or R - determine an
appropriate range based on impedance. The following table presents
appropriate ranges for C and L when D is equal to or smaller than 0.1 and
those when θ is equal to or smaller than 6.
