Introduction
INTRODUCTION
The DS200 Channel Graphing Multimeter is an automotive industry compact 2 channel Bluetooth graphing multimeter connected to a smart
device application that allows for both the initial information to be read and received, but also is opening the gateway into the future of data
intelligence and interpretation. The meter connected to the smart device application, and it can be one of many that can be connected to the
application to provided data for interpretation and analysis to give the user intelligent data; and it is a 2-channel intelligent system; this is the first
set towards data intelligence.
The DS200 Channel Graphing Multimeter (hereafter “The Meter”) is a battery powered multimeter capable of handheld and remote.
The Meter meets CAT III IEC 61010-1 3rd edition and 61010-2-030 standards. Overvoltage category III (CAT III) defines a level of safety
appropriate for the transient over voltages present in fixed equipment installations at the distribution level. This includes the mainsinstallation of a
building, distribution boards, busbars, and permanently connected equipment. Do not use this multimeter for CAT IV circuits, which includes any
mains circuits not protected by a building’s breakers.

Safety Information
SAFETY INFORMATION
WARNING: Denotes a potentially hazardous situation that may result in injury or death
CAUTION: Denotes a potentially hazardous situation that may result in damage to the meter
NOTE: Denotes a situation that may result in degraded or incorrect measurement
§ Use caution in the operation of this device. Improper use may
result in injury or death. Read this user manual before operating
the meter.
§ Always remove leads before opening the case.
§ Do not operate the meter unless it is fully assembled with both
case screws tight.
§ Only use appropriately rated fuses.
§ Always check for damage before use. Pay special attention tothe
test leads for signs of damaged insulation or exposed
conductors. Immediately replace damaged leads.
§ Only use test leads that are rated to at least CAT III 600VKeep
fingers behind the guards on the leads.
§ Use caution working with voltages above 30VAC rms, 42VACpeak,
or 60VDC. Voltages this high pose risk of shock.
§ Never apply more than 600V between any terminal and earth
§ ground.
§ Do not apply more than 2.0V to the auxiliary terminal with respect
to Common. Doing so may draw unexpected currents and trigger
protection circuits. In this event, basic functionalitywill automatically
return within one minute. Accuracy may be adversely affected for
up to five minutes.
§ Error messages may appear on the user interface. Read these
messages for further information

Basic Measurement Instructions
Measuring Voltage
MEASURING VOLTAGE
WARNING: Risk of Electrocution. For determining whether a circuit is “live” exercise caution if the meter does not report a voltage. This
may indicate a poor connection to the circuit being tested. Make sure the probe tips are fully in contact with the circuit before assuming the
circuit is safe.
Two of the DS200 Multimeter’s input terminals are capable of making basic
voltage measurements:
The V terminal can measure up to 600V RMS and is intended for traditional
AC and DC voltage measurements.
The Ωterminal can measure up to 1V peak (~0.7V RMS for pure-sineAC) and
allows for several new measurement techniques described later in this
manual.
See the ratings section for further details on the measurement ranges.

Basic Measurement Instructions
Measuring Current with the Internal Current Shunt
MEASURING CURRENT WITH THE INTERNAL CURRENT SHUNT
WARNING: Exercise care when connecting in series with a circuit, especially those containing motor(s). Sudden disconnects may create
higher than expected voltages due to inductive kick.
WARNING: Perform a Fuse Check before measuring currents withthe internal
current shunt. Exercise caution in determining whether a circuit is “live” if the
meter does not report a current. This may indicate either a poor connection or
a blown fuse.
NOTE: AC current range is limited by the instantaneous current. Peaks above
the listed limits will result in incorrect readings. Derate AC current limits with
high crest factors accordingly.
§ Disconnect power from the circuit to be measured.
§ Break the circuit and wire the meter in series through the “A” and “C”
terminals.
§ Positive DC current flows into the “A” terminal.

Basic Measurement Instructions
Measuring Current with an External Current Shunt
MEASURING CURRENT WITH AN EXTERNAL CURRENT SHUNT
NOTE: This function may not be compatible with all scan tools. Please verify its compatibility before using it.
WARNING: This measurement mode is capable of measuring currents of many orders of magnitude larger than is typically possible with a
handheld meter. Exercise caution while interfacing high ampacity circuits.
NOTE: The accuracy of this measurement mode depends on the
accuracy of the external current shunt used. Account for this ac-
curacy dependency in your measurements.
The Ωterminal can measure small voltages, with a resolution of as
fine as 25nV per count and a noise floor as low as 1µV. This can be
used to with external current shunts to measure currents over a very
wide dynamic range. See the ratings section to guide shunt size
selection.
It is possible to use the existing wiring for the current shunt, and in
doing so take rough current measurements without breaking the
circuit.
With very low voltages it is recommended to minimize the loop area
of the measurement probes by either twisting them together or
using a BNC adaptor.

Basic Measurement Instructions
Measuring Resistance
MEASURING RESISTANCE
NOTE: Do not measure resistance on a live circuit. Doing so will result in incorrect readings and may engage the internal protection
circuitry. Should this occur, wait 5 minutes before taking further measurements.
§ Resistance is measured between the Ωand C terminals. Polarization is not important.
§ The meter uses a 100nA test current in its MΩranges and a 100uA test
current in its kΩranges.

Basic Measurement Instructions
Diode Testing
DIODE TESTING
NOTE: Do not use the diode test functionality while connected to a live circuit. Doing so will result in incorrect readings and may engage
the internal protection circuitry. Should this occur, wait 5 minutes before taking further measurements.
§ To test diodes or other silicon junction devices, a test current is
pushedthrough the device under test and the resulting voltage is
measured.
§ Positive test current flows out of the Ωterminal and into the C terminal.
The test current is 100µA.

Basic Measurement Instructions
Using a BNC Adaptor
USING A BNC ADAPTOR
NOTE: This function may not be compatible with all scan tools. Please verify its compatibility before using it.
The 4 terminals are arranged with 0.75” spacing to allow for use of a standard BNC adapter. Measurements using the A or Ωterminals can be used
with the C terminal as usual.
§ To use a BNC adapter with the “V” input, use the “A” terminal as the common input. The “A” and “C” terminals are internally connected with a
low impedance (<=20mOhms).
