Description
The Tempo MM810 Digital Multimeter is a hand-held testing device with the following
measurement capabilities: AC and DC voltage, AC and DC current, frequency, resistance,
capacitance, and duty cycle of logic level signals. It also checks diodes and veries continuity.
The meter features true RMS AC measurements, a relative zero mode, data hold mode, and an
intelligent automatic power off.
Other specialized capabilities and functions common to all meters include:
• Dual display shows two measurements, such as AC voltage and frequency, at the same time.
• Backlit LCD for reading in dim conditions.
• Beep-Jack™ audible warning alerts the user with a beep and an error message on the LCD if
the test lead is plugged into the mA/μA or A input terminal while the selector switch is not in

Using the Features
All Models
• Dual Digital Display: These meters can display two measurements, such as AC voltage
and frequency, at the same time. Display combinations are shown using large symbols to
indicate the measurement on the primary display and small, raised symbols to indicate the
measurement on the secondary display. For example, “VACHz” means the primary display
contains the AC voltage measurement, and the secondary display contains the frequency
measurement.
• SELECT: Press momentarily to toggle between functions, or to toggle between AC and DC
when measuring current and millivolts.
• 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.
Note: When using MAX-MIN, HOLD, or Δ mode, pressing RANGE will cause the meter to exit
that mode.
• Δ: Finds the difference between two measurements. While taking a measurement, press Δ to
set the display to zero. The Δ icon will appear on the display. Take the second measurement.
The value on the display will be the difference between the two measurements.
Press again to exit this mode.
• HOLD : Press momentarily to hold the present value on the display. Press again to exit this
mode. This feature does not affect the bar graph.
• : Press and hold until backlight illuminates. Press and hold again to turn off. The
backlight automatically turns off after approximately 30 seconds to extend battery life.
• Automatic Power Off: To extend battery life, the meter will shut itself off after approximately
30 minutes of inactivity. To restore power, press either the SELECT, RANGE, Δ, or HOLD
button momentarily, or turn the selector to OFF and then back on. To disable this feature,
press SELECT while turning the meter on.
• Disabling the Beeper: Hold down the RANGE button while turning the meter on to temporarily
disable the beeper feature. Turn the selector to OFF and then back on to enable the beeper.
AC Measurement
AC measurements are usually displayed as RMS (root mean square) values. The RMS value
is equal to the value of a DC waveform, which would deliver the same power if it replaced
the time-varying waveform. Two AC measurement methods are average-responding RMS
calibrated and true RMS-reading.

MM810A
8 9
The average-responding RMS calibrated method takes the average value of the input signal
after full wave rectication, multiplies it by 1.11, and displays the result. This method is
accurate if the input signal is a pure sine wave.
The true RMS-reading method uses internal circuitry to read the true RMS value. This method
is accurate, within the specied crest factor limitations, whether the input signal is a pure sine
wave, square wave, triangle wave, half wave, or signal with harmonics. The ability to read true
RMS provides much more measurement versatility. The Tempo MM810 is a true RMS meter.
The Waveforms and Crest Factors table shows some typical AC signals and their RMS values.
Measurement Categories
These denitions were derived from the international safety standard for insulation
coordination as it applies to measurement, control, and laboratory equipment. These
measurement categories are explained in more detail by the International Electrotechnical
Commission; refer to either of their publications: IEC 61010-1 or IEC 60664.
Measurement Category I
Signal level. Electronic and telecommunication equipment, or parts thereof. Some examples
include transient-protected electronic circuits inside photocopiers and modems.
Measurement Category II
Local level. Appliances, portable equipment, and the circuits they are plugged into. Some
examples include light xtures, televisions, and long branch circuits.
Measurement Category III
Distribution level. Permanently installed machines and the circuits they are hard-wired to.
Some examples include conveyor systems and the main circuit breaker panels of a building’s
electrical system.
Measurement Category IV
Primary supply level. Overhead lines and other cable systems. Some examples include cables,
meters, transformers, and other exterior equipment owned by the power utility.

AC Measurement
AC measurements are usually displayed as RMS (root mean square) values. The RMS value is equal to
the value of a DC waveform, which would deliver the same power if it replaced the time-varying wave-
form. Two AC measurement methods are average-responding RMS calibrated and true RMS-reading.
The average-responding RMS calibrated method takes the average value of the input signal after full
wave rectification, multiplies it by 1.11, and displays the result. This method is accurate if the input
signal is a pure sine wave.
The true RMS-reading method uses internal circuitry to read the true RMS value. This method is accu-
rate, within the specified crest factor limitations, whether the input signal is a pure sine wave, square
wave, triangle wave, half wave, or signal with harmonics.The ability to read true RMS provides much
more measurement versatility. The Greenlee DM-810A, DM-820A, DM-830A, and DML-430A are true
RMS meters.
The Waveforms and Crest Factors table shows some typical AC signals and their RMS values.
Waveforms and Crest Factors

Crest Factor*
(x)1.414 1 1.73 2
* The crest factor is the ratio of the peak value to the RMS value; it is represented by the Greek
letter x.
AC + DC True RMS
AC + DC true RMS calculates both of the AC and DC components given by the expression
when making measurements and responds accurately to the total effective RMS value regardless of the
waveform. Distorted waveforms with the presence of DC components and harmonics may cause:
• Transformers, generators, and motors to overheat
• Circuit breakers to trip prematurely
• Fuses to blow
• Neutrals to overheat due to the triplen harmonics present on the neutral
• Bus bars and electrical panels to vibrate
The DM-830A and DML-430A are AC + DC true RMS meters.

* Noise rejection is the ability to reject unwanted signals, or noise.
• Normal mode voltages are AC signals that can cause inaccurate DC measurements. NMRR
(Normal Mode Rejection Ratio) is a measure of the ability to lter out these signals.
• Common mode voltages are signals present at the COM and + input terminals, with respect
to ground, that can cause digit rattle or offset in voltage measurements. CMRR (Common
Mode Rejection Ratio) is a measure of the ability to lter out these signals.
