•Always discharge the filter capacitors in a power supply circuit before
attaching the test leads.
•Never connect a voltage source to the DVM892 when it is in current (DCA
or ACA) mode, resistance or continuity mode.
•Always turn off the power and disconnect the test leads prior to replacing
the battery or fuse.
•The user should only operate the multi-meter when the back cover is in
place and securely fastened.
•When carrying out measurements on TVs or switching power circuits, you
should always remember that high voltage pulses may occur at the test
points. These pulses may damage the meter.
c. Maintenance
Your DVM892 is an example of superior design and craftsmanship. The
following suggestions will help you keep the device in perfect working order:
•Do not expose the device to water. Wipe it dry immediately if it should get
wet.
•Use and store the multi-meter under normal temperatures. Extreme
temperatures may shorten the life of the device or damage the battery.
•Handle the multi-meter with care. Dropping it may damage the circuit
boards or the housing and may cause the DVM892 to malfunction.
•Replace an old or weak battery with a fresh one of the required size and
type.
•Remove the battery during long periods of inactivity. This will protect the
multi-meter from possible leakage.
•Disconnect the test probes prior to opening the housing.
•A blown fuse should be replaced with an identical one (see §6).
•Do not use this device in case of malfunction or if anomalies are detected.
Have it repaired by qualified personnel.
•Do not use the multi-meter unless the back cover is in place and fully
fastened.
•Use a soft cloth and a mild detergent for cleaning purposes. Never use
abrasives or solvents on the meter.
2. Accessories
•set of test leads
•K-type thermocouple (400°C)
•1 battery of 9V
•1 user manual
•1 holster: it protects the device and ensures comfortable operation. Refer
to the illustrations on page 2 of this manual.
A & B. Use one of the two supports to place the device on a table or a
desk.

4. Connect the black test lead (-) to the "COM" terminal and the red test
lead (+) to the other terminal of the adaptor socket.
5. The display will show the approximate hFE-value at the moment of
testing. Base current 10µA, Vce 2.8V.
i. Measuring Temperature
1. Connect the black test lead (-) to the "COM" jack and the red test lead
(+) to the "mA" jack.
2. Select the TEMP-range with the FUNCTION switch.
3. Insert the plug of the K-thermocouple in the adaptor socket according
to the indicated polarity.
Remark: push the temperature probe firmly into the socket.
4. Connect the black test lead (-) to the "COM" terminal and the red test
lead (+) to the other terminal of the adaptor socket.
5. The display will show the temperature.
Remark: without the thermocouple in place, the display will show the
ambient temperature.
j. Measuring Frequency
1. Connect the black test lead (-) to the "COM" jack and the red test lead
(+) to the "VΩHz" jack.
2. Select the "KHz" range with the FUNCTION switch and connect the test
leads to the source or load to be tested.
Remarks:
Do not apply more than 220Vrms to the input.
Use shielded cable for measuring a weak signal in a noisy
environment.
k. Automatic Power off
1. The device will be deactivated automatically when the FUNCTION and
RANGE switch has not been used for 15 minutes. This energy-saving
feature extends the life of your battery.
2. The meter will be reactivated if the FUNCTION and RANGE switch is
turned or if the power switch is pressed again.
5. Specifications
Maximum accuracy is guaranteed for a one-year period after calibration.
Ideal circumstances require a temperature of 23°C (± 5°C) and a max.
relative humidity of 75%.
