polarity indications marked on both the battery cell and the
battery holder. Insert the positive end of the battery cells
first.
After installing the cells, reinstall the instrument in its case and
secure the ten screws.
Power Up
Plug the power cord into the R1L-BIR1 front panel receptacle,
and plug the other end into a standard AC outlet. For battery
operation (with charged battery cells), this step is omitted.
Turn on the POWER rotary switch. Note that this switch turns
on both line and battery power.
Charging the Battery Cells
Prior to battery operation, it is recommended the R1L-BIR1
Microohm/Bond Meter be plugged into AC power for at least
14 hours to charge the battery cells. To charge the battery
cells, the Power Switch must be turned ON, and the Range
Switch should be set to 20 Ω. With the Range Switch set to
lower ranges, the charge rate decreases and the batteries will
be discharged, especially on the 2 mΩ range, even with no
resistance connected to the instrument. (However, the
discharge rate in this range will permit operation for at least
14 hours with no resistance connected.)

OPERATING INSTRUCTIONS
The R1L-BIR1 is designed for field or bench-top operation. Use appropriate cables connecting their terminations to the four binding posts marked +I, +E, -E, and -I.
DO NOT TOUCH THE BINDING POSTS WHEN THEY ARE
CONNECTED TO EXTERNAL CIRCUITS. LETHAL VOLTAGES
3.1 Rotary Switch Functions
Operation of the Model R1L-BIR1 is simple. There are only two
switches.
The RANGE rotary switch manually scrolls through the five
ranges.
Full scale on any range may be described as 2,000 counts
(actually 1,999), since this is a 3½ digit meter. If the readings
are exceeding 1,999 counts, step to the next higher range. If
the readings are less than 2,000 counts, step down a range,
so that it will read 1,999 counts, or less. The decimal point is
located automatically for the correct reading.
If the selected range is too low for the value of the resistor
under test, the display will show over-range.
The POWER rotary switch turns on the power to operate the
unit or turns off the power to the unit. The appearance of the
display will show that power is on; absence of the display
indicates that either power is off, batteries are discharged, or
there is some malfunction. Note that when power is turned
off, it may take several seconds to discharge circuit capacity
to completely blank the display. The black markings seen have
no effect and disappear when power is turned back on.

WARNING
FROM OTHER COMPONENTS AND APPARATUS.
3.2 General Theory Of Operation
Measurement Principle
A 4-terminal measurement method is used to determine the
resistance of the item under test. This method allows the
accurate measurement of low values of resistance in spite of
the other resistances present in the connection leads. A known
current is supplied to the item under test via two wire leads
connected to the +I and -I binding posts on the R1L-BIR1
Microohm/Bond Meter front panel. Two other wire leads
connected to the +E and -E binding posts on the R1L-BIR1
front panel sense the voltage developed across the resistance
under test due to the supplied known current. The R1L-BIR1
then calculates the resistance of the item under test utilizing
Ohm's law, and displays it on a 3 ½ digit display.
Kelvin Clip Cable Description
A Kelvin clip consists of two opposing jaws of an alligator style
clip which are insulated from each other, so one jaw may be
used to connect a source of current to the resistance under
test, and the other jaw used to measure the voltage at the test
point. The two jaws are spring loaded to clamp onto a cylinder
of ½ inch diameter or less.
OPERATING THE R1L-BIR1 MICROOHM/BOND METER AND
TAKING RESISTANCE MEASUREMENTS ON A POWERED OR
ENERGIZED COMPONENT COULD CAUSE SERIOUS HARM
TO THE OPERATOR AND/OR DAMAGE THE R1L-BIR1. BE
SURE THE ITEM TO BE MEASURED IS DISCONNECTED
If the battery cells have not been installed, refer to section
2.2. Battery only operation will result in the most stable and
accurate readings. The R1L-BIR1 may be operated while
charging the batteries, however it will not conform to
specifications in this configuration.

OPERATING INSTRUCTIONS
NOTE: The amount of current available for charging the
battery decreases as lower resistance ranges are selected. In
the 2 mΩ range, the current supplied to the resistance under
test exceeds the charging current, and the battery will be
drained.
To obtain the best accuracy, allow the R1L-BIR1 to warm up
for 15 minutes on the 20 Ω range before making
measurements. Even if in battery operation, this will not cause
appreciable battery discharge.
Using the Kelvin Clip cables
Plug one Kelvin Clip cable dual banana plug across the +E and
+I binding posts, and plug the other Kelvin Clip cable dual
banana plug across the -E and -I binding posts. Note that in
both cases, the small "I" marked on the dual banana plug
should go into the respective I binding post.
If Kelvin Clip cables are not used, a pair of shielded cables
may be utilized. As occurs in the Kelvin Clip cables in the
above paragraph, one cable should have its shield connected
to the “+I” binding post and its center conductor connected to
the +E binding post. Similarly, the other cable should have its
shield connected to the -I binding post and its center
conductor to the -E binding post. It is also recommended that
the resistance of the cables should not exceed 350
mΩ/conductor.
NOTE: Particularly in the 2 mΩ range, where a test current of
approximately 1.4 A is used, excessive lead resistance will
prevent an accurate measurement.
Set the Range Switch to the desired measurement range and
read the resistance on the liquid crystal display. If the
resistance is higher than the selected range, the display will
show a "1" and three blank digits, indicating over-range. The
decimal point will also appear in the proper location for the
selected range.

OPERATING INSTRUCTIONS
After prolonged operation on battery power, when the battery
voltage approaches the end of its useful range, the "LO BAT"
indicator will be seen on the display. Although the battery cells
are not fully discharged and they will not be damaged by
additional use, this is a warning to the operator that the
battery cells need to be charged.

PRINCIPLES OF OPERATION
SECTION 4
PRINCIPLES OF OPERATION
Power Supply
The internal switching power supply U8 accepts nominal line
voltages between 90 and 250 VAC 50/60 Hz, allowing
operation worldwide. C1, C2, U1, R1, R2 and R101 form a
constant current regulator set to approximately 758 mA for
charging the battery. D5 is used to isolate the AC power for
the battery. D7 serves to clamp the voltage to less than 5 V
when the battery is disconnected. The negative 3.6 volt power
supply for U2 and U10 is developed by U5.
Test Current Path
The test current used to perform the resistance measurement
originates from the battery + terminal connected to the +3.6
V power symbol at the emitter of Q1. It flows through Q1 into
the COM1 terminal of SW1 and out of the terminal selected by
the switch for the measurement range chosen. Each pole of
the COM1 section of SW1 is connected to a different tap on
the current sensing resistor string made up of R13, R48, R50,
R52 and R54. The test current flows into the sense resistor
string at the tap selected, out of R54 into D3 and out of D3 to
the I+ test jack. The external test leads conduct the current
through the resistance being measured and back to the I- test
jack, where it returns to ground and then to the battery terminal.
Test Current Regulator
The test current is controlled to a constant value for each
range with a feedback loop. The main loop amplifier is U9A.
The output of U9A controls the conduction of Q1 using Q2,
such that if the output voltage of U9A increases, the test
current increases. The inputs of U9A compare the voltage
across the current sensing resistor string with a 3 volt
reference voltage produced by U4, the voltmeter IC. The
voltage across the sensing resistor string is maintained at 1.5
V, half the value of the reference voltage because R9 and R11

PRINCIPLES OF OPERATION
are twice the value of R8 and R9. The reference voltage of 3
V is present between the VREF signal at one end of R9 and the
+3.6 V power supply present at one end of R11. The voltage
at one end of the sensing resistor string is present at U11A
pin 1 which feeds R8. The voltage at the other end of the
sensing resistor string is present at U11B pin 7 which feeds
R10. U11A and U11B are very high input impedance buffer
amplifiers which sense the voltage across the current carrying
portion of the sensing resistor string without causing errors in
the test current. R127, R129 and CR1 provide overvoltage
input protection for pin 3 of U11A, and similarly R46, R128
and CR2 for U11B. U2B will shut off the current source if the
voltage on the I+ binding post becomes less than about -3 V.
Test Current Adjustment
The test current on the 2 milliohm range is 1.4 amps. It is
very stable, but not adjustable. The 1.4 A current stability is
determined by the stability of R54, the 3 V reference
developed by U4 and to a minor extent other circuit
components. The test currents on the four other ranges are
adjusted to approximately 1/10, 1/100, 1/1000 and 1/10000
of the actual value of the 2 milliohm range test current during
the calibration/ adjustment process. Trimpots R53, R51, R49
and R114 are used for this adjustment, and are adjusted
sequentially in that order. Adjusting the current affects the
readings, so current adjustment INDEPENDENT of the
readings adjustment is not possible.
Voltage Measurement
The voltage across the resistance being measured is amplified
by U10A, U10B and U9B. The E+ and E- test jacks are the
input to this differential amplifier, and the output is connected
to the voltmeter IC U4 pins 38 and 39. R130, R131, R141,
R142, CR3 and CR4 provide overvoltage input protection.
U10A, U10B, R132, R133 and R134 provide a differential gain
of 5: the voltage between U10A pin 1 and U10B pin 7 is 5
times the voltage between E- and E+. U9B provides voltage
gain of 10, and develops its output between VREF at pin 40 of
U4 and VIN+ at pin 39 of U4. An adjustable bipolar offset
voltage is added to this output by R143 before it is applied to

Page 17
PRINCIPLES OF OPERATION
VIN- at pin 38 of U4. C18 and 140 are a low pass filter to
reduce noise.
The voltmeter IC U4 converts the amplified voltage across the
resistance being measured into a displayed reading. Because
the test current is precisely regulated along with the various
gains chosen in the circuit, the displayed value is directly
proportional to the resistance being measured. U4 develops a
reference voltage of 3 V between pins 8 and 40. The reference
is divided by the resistor string R31, R32, R146 and R143.
R146 provides an adjustable voltage used as the analog to
digital conversion reference to pin 44. R143 provides an
adjustable zero reading.
Display
U4 directly drives the LCD, except for the decimal points and
the LOBAT indicator. The decimal point associated with the
range selected is displayed when the range switch SW1
provides a +3.6 V signal to one of the inputs of U7. The LOBAT
signal is displayed when U2A detects the voltage at pin 40 of
U4 falls below ground. Since this pin is maintained by U4 at
the reference voltage of 3 V below the battery voltage, LOBAT
will be displayed when the battery is less than approximately
3 V.

After trouble-shooting and repair, the instrument must be recalibrated in accordance with 5.4 above. Disassembly
• First remove the line cord and any other connecting wires.
Then remove the ten screws of the top (display) panel.
Carefully lift the unit out of its cabinet. Remove the three
battery cells.
• Remove the four screws that secure the battery plate.
• Loosen the set screws in the knobs for the Power and
Range switches, and remove these knobs.
• To separate the printed circuit board from the front panel,
remove the two screws and two standoffs appearing in a
rectangular pattern around the LCD and control switches.
Remove the four nuts from the binding post connections.
Re-assembly
To reassemble the unit, repeat the above steps in reverse
order, taking care to install the lockwashers on the proper
screws.
5.6 Preparation for Shipment
The original shipping carton is not reusable.
Remove the battery cells prior to shipment (or inactive storage of 30 days or more) and package them separately. Disassemble the R1L-BIR1 as per section 5.5, and extract the negative end of the battery cells first.
Packaging must provide sufficient resilient material, in
accordance with standard packaging practices, to prevent
excessive shock to the power supply and display during
shipment.

5.7 Overhaul Instructions
The R1L-BIR1 is an all solid-state unit and requires no
periodic overhaul, other than routine cleaning, inspection of
cables per section 5, and calibration per section 5.4.
However, some disassembly is required to remove and install
the batteries. This level of disassembly is detailed in section
2.2 and battery cells should be removed at the negative end
first.
Tools and test equipment used for disassembly, calibration,
and troubleshooting of the R1L-BIR1 are listed in section 5.3.
Troubleshooting suggestions are given in section 5.5.
The only component expected to require replacement is the
battery. The battery designation is listed on the Replacement
Parts List, with battery cell removal and installation
instructions given in section 2.2.

SERVICE INFORMATION
Preparation for Calibration or Repair Service
Once you have verified that the cause for R1L-BIR1
malfunction cannot be solved in the field and the need for
repair and calibration service arises, contact TEGAM customer
service to obtain an RMA, (Returned Material Authorization),
number. You can contact TEGAM customer service via the
TEGAM website, www.tegam.com
(All Locations) OR 800.666.1010 (United States Only).
The RMA number is unique to your instrument and will help us
identify you instrument and to address the particular service
request by you which is assigned to that RMA number.
Of even importance, a detailed written description of the
problem should be attached to the instrument. Many times
repair turnaround is unnecessarily delayed due to a lack of
repair instructions or of a detailed description of the problem.
This description should include information such as
measurement range, and other instrument settings, type of
components being tested, are the symptoms intermittent?,
conditions that may cause the symptoms, has anything
changed since the last time the instrument was used?, etc.
Any detailed information provided to our technicians will assist
them in identifying and correcting the problem in the quickest
possible manner. Use a copy of the Repair and Calibration
Service form provided on the next page.
Once this information is prepared and sent with the instrument
to our service department, we will do our part in making sure
that you receive the best possible customer service and
turnaround time possible.
