1.1
Precautions and safety measures
1.1.1 Before using
You have just acquired a DMM240 RMS multimeter. Thank you for your
confidence. It measures AC/DC Voltage, AC/DC Current, Resistance,
Frequency (electrical & electronic), and test diodes and Continuity. It
features a waterproof, rugged design for heavy duty use. Proper use
and care of this multimeter will provide many years of reliable service.
This multimeter complies with the IEC 61010 standard concerning
electronic measurement instruments. For your own safety and to
prevent damage to the instrument, follow the instructions in this manual.
Be careful to adhere to storage conditions.
This handheld autonomous instrument was designed for:
∗ Indoor use
∗ Use in pollution 2 degree environments
∗ In altitudes lower than 2,000 meters
∗ In temperatures ranging from 5°C to 40°C
It can be used up to 1000 V on category III circuits, or 600 V on
category IV circuits.
Definition of installation categories (cf. IEC 664-1)
CAT I: Circuits protected by devices designed to
minimize transient overvoltage at a low level.
E.g. protected electronic circuits.
CAT II: Domestic or analogue appliances’ power supply
circuits that can include average value transient
overvoltage.
E.g. power supply to domestic appliances and portable tools.
CAT III: Power appliances’ supply circuits that can include high
transient overvoltage.
E.g. machinery or industrial apparatus power supply.
CAT IV: Circuits that can include very high transient overvoltage.
E.g. energy inputs
For safety reasons, you should only use leads and measurement
accessories suitable for use with the voltage and overvoltage category
of the circuit to be measured that comply with the IEC 61010 standard.
Do not use the instrument or its leads if they appear damaged.
1.1.2 When using the instrument
- Never exceed the protection limiting values indicated in the
specifications for each type of measurement.
- When the multimeter is connected to the circuits to be measured, do
not touch any unused terminals.
- Before changing function, disconnect the measurement leads from the
circuit measured.
- Never measure resistances or test diodes, etc., on a live circuit.

4mA=0%, 20mA=100%, and 24mA=125%.
3.12 Autoranging/Manual range selection
When the multimeter is first turned on, it automatically goes into
Autoranging and this automatically selects the best range for the
measurements being made. This is generally the best mode for most
measurements. For measurement situations requiring manual selection,
proceed as follows:
1. Press the RANGE key. The “AUTO” display indicator will turn off.
2. Press the RANGE key several times to scroll through the available
ranges until the one you want is displayed.
3. To exit the Manual selection mode and return to Autoranging, press
and hold down the RANGE key for 2 seconds.
Manual ranging does not apply to temperature measurements.
DMM240
27
Chapter II
3.13 MAX/MIN
When using the MAX/MIN function in autoranging mode, the multimeter
will “lock” into the range that is displayed on the LCD when MAX/MIN is
activated. If a MAX/MIN reading exceeds that range, “OL” will be
displayed. Select the adequate range before entering MAX/MIN mode.
1. Press the MAX/MIN key to activate the MAX/MIN measurement mode.
The "MAX" icon will appear. The multimeter will display and hold the
maximum measurement until another maximum value is reached.
2. Press the MAX/MIN key again to display the "MIN" icon. The
multimeter will display and hold the minimum measurement until
another minimum value is reached.
3. To exit MAX/MIN mode, press and hold the MAX/MIN key for 2 s.
3.14 Relative mode
Relative mode enables relative measurement results to be obtained in
relation to a stored reference value. The displayed value is the
difference between the stored reference value and the value measured.
Relative mode does not apply to the 4-20mA function.
1. Perform the measurement as described in the operating instructions.
2. Press the REL key to store displayed measurement. The "REL"
indicator is displayed.
3. The display will now indicate the difference between the stored
reference value and the value measured.
4. Press the REL key to exit relative mode.
3.15 Backlighting
Press the HOLD/ key down for >1 second to activate or disable
backlighting. Backlighting will automatically disable after 10 s.
3.16 HOLD
The hold function freezes the reading in the display. Press the HOLD
key briefly to activate or to disable the HOLD function.
3.17 PEAK HOLD
The Peak Hold function captures the peak AC or DC voltage or current.
The multimeter can capture negative or positive peaks as fast as 1 ms
in duration. Briefly press the PEAK key, “PEAK” and “MAX” will display.
The multimeter will update the dispay each time a higher positive peak
occurs. Press the PEAK key again, “MIN” will display. The multimeter
will update the dispay each time a lower negative peak occurs. Press
and hold the PEAK key for more than 1 s to exit PEAK Hold mode. Auto
Power Off feature will be disabled automatically in this mode.
28
DMM240
Chapter II
3.18 Low battery indication
When a fresh battery is installed, the battery icon with four lines
above it will be displayed in the lower right corner of the LCD. The lines
will disappear as the battery is used. When the icon appears alone in
the display, the battery must be replaced.
3.19 AUTO POWER OFF
The auto off feature will turn the multimeter off after 15 minutes. To
disable the auto power off feature, hold down the MODE key when
turning the multimeter on. “APO d” will appear in the display. Turn the
multimeter off and then on again to re-enable the auto power off
feature.
4. MAINTENANCE
To avoid electric shocks, disconnect the measurement leads
from any source of voltage before opening the instrument or
battery compartment. Do not use the instrument when it is open or
without locking the battery compartment cover.
This multimeter is designed to provide years of reliable service, if the
following care instructions are followed:
1. Keep the multimeter dry. If it gets wet, wipe it dry.
2. Use and store the multimeter in normal temperatures. Extreme
temperatures can shorten the life of the electronic parts and distort
or melt plastic parts.
3. Handle the multimeter gently and carefully. Dropping it can
damage the electronic parts or the case.
4. Keep the multimeter clean. Wipe the case occasionally with a
damp cloth. DO NOT use chemical substances, cleaning solvents,
or detergents.
5. Use only new batteries of the recommended size and type.
Remove the old or used battery so it does not leak and damage
the instrument.
6. If the multimeter is to be stored for a long period of time, the
battery should be removed to prevent damage to the unit.
