Description
The Greenlee DM-200 and DM-210 Digital Multimeters are hand-held testing devices
with the following measurement capabilities: AC and DC voltage, AC and DC current and
resistance. They also check diodes, verify continuity and detect electric fields. In addition, the
DM-210 measures temperature (K-type thermocouples only), frequency and capacitance.
Safety
Safety is essential in the use and maintenance of Greenlee tools and equipment. This
instruction manual and any markings on the tool provide information for avoiding hazards and
unsafe practices related to the use of this tool. Observe all of the safety information provided.
Purpose
This instruction manual is intended to familiarize all personnel with the safe operation and
maintenance procedures for the Greenlee DM-200 and DM-210 Digital Multimeters.

Important Safety Information
This symbol is used to call your attention to hazards or unsafe practices which could
result in an injury or property damage. The signal word, defined below, indicates the
severity of the hazard. The message after the signal word provides information for
preventing or avoiding the hazard.
SAFETY ALERT SYMBOL
Immediate hazards which, if not avoided, WILL result in severe injury or death.
Hazards which, if not avoided, COULD result in severe injury or death.
Hazards or unsafe practices which, if not avoided, MAY result in injury or property
damage.
Read and understand this material before operating or servicing
this equipment. Failure to understand how to safely operate this
tool can result in an accident causing serious injury or death.
Electric shock hazard:
Contact with live circuits can result in severe injury or death.

Important Safety Information
Electric shock hazard:
• Do not apply more than the rated voltage between any two input terminals, or
between any input terminal and earth ground.
• Do not contact the test lead tips or any uninsulated portion of the accessory.
Failure to observe these warnings can result in severe injury or death.
• Do not operate with the case open.
• Before opening the case, remove the test leads from the circuit and shut off the unit.
Failure to observe these warnings can result in severe injury or death.
Electric shock and fire hazard:
• Do not expose this unit to rain or moisture.
• Use this unit for the manufacturer’s intended purpose only, as described in this
manual. Any other use can impair the protection provided by the unit.
Failure to observe these warnings can result in severe injury or death.
Electric shock hazard:
• Do not use the unit if it is wet or damaged.
• Use test leads or accessories that are appropriate for the application. See the
category and voltage rating of the test lead or accessory.
• Inspect the test leads or accessory before use. The item(s) must be clean and dry,
and the insulation must be in good condition.
Failure to observe these warnings can result in severe injury or death.

Important Safety Information
Do not change the measurement function while the test leads are connected to a
component or circuit.
Failure to observe this precaution can result in injury and can damage the unit.
• Do not attempt to repair this unit. It contains no user-serviceable parts.
• Do not expose the unit to extremes in temperature or high humidity.
See Specifications.
Failure to observe these precautions can result in injury and can damage the unit.
Unless measuring voltage, current or frequency, shut off and lock out power. Make
sure that all capacitors are discharged. Voltage must not be present.
The fuse is an integral part of the overvoltage protection. When fuse replacement is
necessary, see Specifications for the correct type, size and capacity. Using any other
type of fuse will void the overvoltage protection rating of the unit.
Failure to observe this warning can result in severe injury or death.
Set the selector and connect the test leads so that they correspond to the intended
measurement. Incorrect settings or connections can result in a blown fuse.
Using this unit near equipment that generates electromagnetic interference can result
in unstable or inaccurate readings.

Using the Features
• Automatic Power Off To extend battery life, the meter will shut itself off after approximately
30 minutes of inactivity. To restore power, press any button. To disable this feature, press
Select while turning the meter on.
•Select Press momentarily to toggle between functions, or to toggle between AC and DC
when measuring current and volts.
• Range Press once to enter the manual ranging mode. The icon will disappear from
the display. Press repeatedly to step through the ranges. Press and hold to return to the
automatic ranging mode.
• Hz % (DM-210 only) Press momentarily when performing any measurement to display the
frequency. Press again to display the duty cycle as a percentage (%). Press again to exit
this mode.
Note: The sensitivity of the frequency measurement function varies with the measurement
range. To automatically select a sensitivity level, measure the voltage level first, then press
Hz
. If the reading becomes unstable, or if the display is blank, manually change the
sensitivity by momentarily pressing
Range.
• DET Press to use the AC Detective technology. Use this feature to detect the electric field
that surrounds current-carrying conductors. Signal strength is displayed as a series of
dashes on the display.
• Use the multimeter’s built-in antenna (located along the top, near the LCD) for tracing
live circuits or locating a break in a wire.
• For more precision, such as distinguishing between current-carrying and ground wires,
connect a test lead to the + input terminal and use it as a probe.
• Relative ∆(DM-210 only) Finds the difference between two measurements. While taking a
measurement, press Rel ∆to set the display to zero. The ∆icon will appear on the display.
Take the second measurement. The value on the display will be the difference between the
two measurements. Press and hold to exit this mode.
• Hold Press momentarily to hold the present value on the display. Press again to exit this
mode.

Operation
1. See the Settings Table. Set the selector to the proper setting, press Select (when
instructed to do so), and connect the test leads to the meter.
2. See Typical Measurements for specific measurement instructions.
3. Test the unit on a known functioning circuit or component.
• If the unit does not function as expected on a known functioning circuit, replace the
batteries and/or fuses.
• If the unit still does not function as expected, send the unit to Greenlee for repair.
4. Take the reading from the circuit or component to be tested.
Electric shock hazard:
Contact with live circuits can result in severe injury or death.
