1. Introduction
1.1 Use
Fast and accurate measurements of ultra-small resistances can be made using the RESISTOMAT®
type 2316 milliohmmeter. With its rugged table-top case and membrane keypad, this instrument
is designed for both laboratory use and harsh industrial environments.
Temperature-compensated resistance-testing of wires and coils is possible using a Pt 100 sensor
or pyrometer to measure the temperature of the device under test. The instrument then corrects
the resistance to e.g. 20 °C (selectable).
The meter has a huge range of applications such as measuring:
ltransformer/motor windings
lcoils of any kind
lcables and wires on the drum or as meter samples
lswitch and relay contacts
lheating elements
lfuses
lconnections and contacts to power rails and much more.
For a cooling curve recording with freely selectable time interval a data logger for up to 1000 values
is available.
Complete control capability via the RS232 PC interface means that fully automatic test stations
can be set up. The meter includes a PLC interface for integration in production process controllers.
A 2-way comparator with PLC and relay switching outputs is also provided for classication and
selection of the devices under test.
1.2 Description
The meter works on the basis of the proven four-wire measurement method in which test-lead
resistances and contact resistances are eliminated. The measurement technique also compensates
automatically for any thermal EMFs in the measurement circuit. The instrument leads are monitored
for damage by a built-in detector.
Of course the meter includes temperature compensation for any type of material under test such
as copper, aluminum, brass, tungsten etc. using an external Pt 100 sensor or external infrared
thermometer (accessory) to measure the temperature. A special circuit for protecting the measure-
ment input when measuring high-inductance devices has been developed to prevent damage to
the meter from voltage peaks produced when disconnecting the device under test.
If there is a requirement to test devices using different parameters in an automatic test setup, then
up to 16 device settings such as measuring range, limits, temperature coefcient etc. can be saved.
All device-specic settings are shown on the display.
The settings can be retrieved via the keypad or PLC interface using a bit pattern (4 bits). Of course
all device settings can also be made via the RS232 interface.
A backlit, high-contrast LCD display is used for displaying the readings, so it is extremely easy to
read the measurement in both dark and well-lit rooms.

2. Preparations for use
2.1 Unpacking the unit
The instrument weighs 3.5 kg and is packaged accordingly to protect against shock.
Unpack the instrument carefully and verify that all items are present.
This normally includes: 1 RESISTOMAT®model 2316 milliohmmeter
1 power lead
1 copy of this manual
Inspect the instrument carefully for damage.
If you suspect that the instrument has been damaged during shipping, notify the delivery company
immediately.
The packaging should be retained for examination by a representative of the manufacturer and/or
the delivery company.
The RESISTOMAT®model 2316 should be shipped only in its original packaging or in packaging
capable of providing an equivalent degree of protection.
2.2 Usingtheinstrumentforthersttime
If condensation has formed on the instrument, make sure that the instrument is completely dry
(including inside) before switching it on.
Connect the instrument to a standard grounding outlet using the power lead supplied.
Warning: The instrument must never be switched on if it shows signs of damage during
shipping.
The case or measurement input can carry life-threatening voltages if the mains
voltage is transferred as a result of damage.
2.3 Supply voltage, power switch and mains fuse
The instrument can be operated with supply voltages of 85 to 264 V AC without presetting the
mains voltage.
The power consumption is about 30 VA.
The fuse rating for a supply voltage of 230 V or 115 V is 0.63 AT.
The mains fuse is located between the mains socket
and power switch on the rear of the unit.
Make sure that the unit is fully disconnected from
the electrical mains before changing the fuse. This
should be done by removing the power lead from the
mains socket; always pull on the connector itself, never
the cable.
Only use original fuses 5 x 20 mm 0.63 AT.

2.4 Power supply and signal-lead connectors
-Only ever use a shielded, twisted cable with shielded connectors for connecting to the standard
RS232 interface connector.
- Always use a Pt100 sensor with shielded cable to connect to the Pt100 connector.
The cable shield must not be in contact with the connector shell if grounding of the sensor is
unclear.
Otherwise currents circulating in a ground loop can cause measuring errors.
- Only one device under test must be connected across the two parallel measurement inputs.
No leads must be plugged into the unused connector for safety reasons.

2.6 Setup and installation
• Ensure that there is an adequate supply of air to prevent heat building up in the instrument.
• Do not place the instrument on surfaces such as carpets or cloths, or near materials such as
curtains or wall hangings that could prevent the air circulating.
• Do not place the instrument at an inclined angle. It should always be used in a horizontal
position.
• Keep the instrument away from apparatus, equipment, machines and installations that
generate strong magnetic elds.
• Do not place heavy objects on the instrument.
• Condensation can form inside the instrument if it is taken directly from a warm room into a
cold room. Wait a few hours before switching on the instrument.
• Make sure that the display panel is not mechanically stressed.
• The instrument must have reached thermal equilibrium.
• Select the installation location so that the instrument is not exposed to extreme temperatures
(operating temperature range 0 to 50° C) or temperature variations, nor to humidity, direct sun-
light, incandescent lamps, dust, oils, organic solvents, other aerosols or severe vibrations or
mechanical shocks. In very dirty industrial environments, it is recommended to use a suitable
protective enclosure.
2.7 Functional test
After switching on the instrument, the following text appears on the display for about 3 s:
Then the instrument switches directly to the measurement menu.
2.8 Calibration
The meter was calibrated before shipping. The calibration history of the instruments used for the
calibration can be traced to the government measurement standard in accordance with DIN ISO
9000ff. The meter should be recalibrated after a period of about one year. Calibration is performed
using the RS232 interface, and should only be performed at the manufacturer’s premises. The
customer can perform the calibration in-house by purchasing the PC software 2316-P001.
2.9 Storage
For long-term storage, pack the unit, along with a desiccant, into an airtight, sealed polyethylene
bag. Do not store the unit where it will be exposed to sunlight or other light sources. Take care to
ensure that nothing comes in contact with the display panel. The storage temperature range is
0 to 70°C. However, to maximize the lifespan of the display, the temperature should not exceed
50°C.

3. Safety instructions
Whilst the hardware and software has been developed and tested in accordance with the state of the art,
they cannot be guaranteed totally free of errors. Thus this instrument or part of this instrument must not be
used to inuence a control system from which risk to life or property can arise directly or indirectly without
additional protection. Maintenance and repair work must only be performed by trained, competent techni-
cal personnel familiar with the associated risks.
• The instrument has two measurement inputs connected in parallel; only one of these inputs must be
used at any one time. No leads must be plugged into the unused connector for safety reasons. The
unused circular socket must be covered with the cap supplied.
• Before starting any measurement, make sure that the device under test does not carry an external
voltage (e.g. mains voltage, voltage generated by a rotating motor etc.).
• Take care when handling inductive devices under test. By the physical nature of these devices, life-
threatening induction voltages can be generated when the test current is disconnected. Read the
instructions in the “Load selection”section. (See section 6.5.3)
• To avoid electric shock, never open the case. The instrument contains no components that can be
maintained, adjusted or calibrated by the customer. The instrument can operate with all standard
mains voltages in the world without needing to be switched over.
• Always replace fuses with fuses of the same type. Never use fuses with different characteristics or
other rated currents. Before changing the fuse, pull out the mains plug and short-circuit the device
under test.
• Should foreign bodies or liquids get inside the unit, disconnect the main lead. Get the instrument
checked over by qualied technical personnel before using it again.
• Always leave repair work to qualied technical personnel.
• If you do not intend using the instrument for a prolonged period, take the mains plug out of the
socket. Always pull on the connector itself, never the cable.
• Should liquid from a broken display escape from the unit and get on your hands, wash your hands
thoroughly using soap and water. Remove any residues of the liquid with acetone or ethanol.
• Always keep the instrument out of rain or away from moisture to prevent a re hazard or the risk of
electric shock.
• Check the mains lead before use.
