2. INTENDED USE
• Measuring and displaying electric parameters in the range of overvoltage category CAT IV up to
max. 600 V or CAT III up to max. 1000 V against ground potential, pursuant to EN 61010-1 and all
lower categories.
• Measurement of direct and alternating voltage up to max. 1000 V
• Measurement of direct and alternating currents up to max. 10 A
• Frequency measuring up to 60 MHz
• Measurement of capacities up to 60 mF
• Measurement of resistances up to 60 MΩ
• Continuity test (<10 Ω acoustic)
• Diode test
• Measurement of temperature from -40 to +1000 ºC
• Display of duty cycle in % (10 – 90 %)
• 1 kHz low pass filter alternating voltage measurement
• Comparison value measurement
• Data memory and data logger for 1000 values with time stamp
• Data transmission to a PC via optical interface
• Date and time display
The measuring functions are selected using the rotary switch. The measuring range selection is
automatic for all measuring functions (except for diode and continuity test). Manual setting is possible
at any time.
The VC890 displays true RMS in both the direct and alternating voltage and current range.
For negative values, the polarity will automatically be displayed with the sign (-).
The two current measuring inputs are secured against overload with ceramic high-performance fuses.
The voltage in the current measuring circuit may not exceed 1000 V in CAT lll or 600 V in CAT IV.
A low impedance (Low Imp) function allows measurement with reduced internal resistance. This
suppresses phantom voltages which could appear in high-resistance measurements. Measurement
with reduced impedance is only permitted in measuring circuits up to max. 1000 V and only for max.
3 s. When the Low Imp button is pressed, a signal will sound and a warning indicator will be displayed.
The multimeter is powered by a standard 9 V alkaline or lithium monobloc battery. Operation is only
permitted with the specified battery type. An automatic power off prevents the battery from draining
prematurely if the device is not used for a period of time (settings: 5 min., 15 min., 30 min. or OFF;
see Chapter “19. Auto Power Off function”). The Auto Power Off function is switched off during data
transmission to a PC via optical interface.
47
Do not operate the multimeter when it is open, when the battery compartment is open, or the battery
compartment lid is missing. The safety mechanism prevents the opening of the battery and fuse lid
when test leads are plugged into the measurement sockets. It also prevents test leads from being
plugged in when the battery and fuse lid is open.
Measurements in damp rooms or under unfavourable environmental conditions are not permitted.
Unfavourable environmental conditions are: dampness or high humidity, dust and flammable gases,
vapours or solvents, as well as thunderstorms or similar conditions such as strong electrostatic fields,
etc.
Use only test leads or measurement accessories which meet the specifications of the multimeter.
For safety and approval purposes (CE), you must not rebuild and/or modify this product. If you use
the product for purposes other than those described above, the product may be damaged. In addition,
improper use can cause hazards such as short circuiting, fire, electric shock etc. Read the instructions

6. PRODUCT DESCRIPTION
The measurements are indicated on a digital display on the multimeter (hereinafter called DMM). The
DMM measured value display comprises 60000 counts (count = smallest display value).
When the device is not operated for a specified time (settings: 5 min., 15 min., 30 min.), it will switch
off automatically. This conserves the battery and allows a longer operating time. The Auto Power Off
function is switched off during data transmission to a PC via optical interface.
The measuring device can be used for do-it-yourself or for professional applications up to CAT IV.
The DMM can be ideally positioned with the positioning bracket on the back for improved readability.
The battery and fuse compartment can only be opened when all test leads are removed from the
measuring device. The test leads cannot be plugged into the measuring sockets when the battery and
fuse compartment is open. This increases user safety.
In the voltage and current measuring range, there is an audio warning with display indicators when
test leads are incorrectly connected. Connect the test leads correctly before measuring.
Rotary switch (4)
The individual measuring functions are selected via a
rotary switch. The automatic range selection “AUTO”
is active in some measuring functions. The appropriate
range of measurement is set for each application
individually. Always begin current measurements with
the largest measuring range (10 A) and switch to a
smaller measuring range as needed.
When the switch is in the “OFF” position, the multimeter
is turned off. Always turn the measuring device off
when it is not in use. Figure 1 shows the layout of the
measuring functions.

11. MEASURING
Do not exceed the maximum permitted input values.
Do not touch any contacts or contact parts if these carry higher voltages than 25 V
ACrms or 35 V DC! This may result in life-threatening danger!
Before starting a measurement, check the connected test leads for damage such
as cuts, cracks, or pinching. Do not use defective test leads! This may result in
life-threatening danger!
Never touch anything beyond the grip area marking on the test prods while
measuring.
Measuring is only possible when the battery and fuse compartment is closed. If
the compartment is open, all measuring sockets are mechanically secured against
insertion.
Only two of the test leads which are needed for measuring may be attached to
the device at one time. For reasons of safety, remove all test leads which are not
needed from the device.
Measurements in circuits >50 V/AC and >75 V/DC are to be performed only by
specialists and trained persons who are familiar with the relative regulations and
the ensuing risks.
If “OL” (for overload) appears on the display, you have exceeded the measuring range.
58
a) Turning on the multimeter
The multimeter is turned on and off with the rotary switch (4). Turn the rotary switch to the appropriate
measuring function. To turn it off, move the rotary switch to the “OFF” position. Always turn the
measuring device off when it is not in use.
b) Voltage measurement “V”

23.MAINTENANCE AND CLEANING
a) General
Calibrate the multimeter annually to guarantee the accuracy of the multimeter over a longer period
of time.
The measuring device is absolutely maintenance-free except for occasional cleaning and the
replacement of fuses.
You can find the fuse and battery replacement instructions below.
Regularly check the technical safety of the device and the test leads, for example
damage to the housing, pinching of the test leads, etc.
b) Cleaning
Always observe the following safety instructions before cleaning the device:
Live components may be exposed when covers are opened or components are
removed, except if this can be done by hand.
The connected lines must be disconnected from the measuring device and all
measuring objects prior to cleaning or repairing the device. Turn off the DMM.
Do not use cleaning agents which contain carbon, petrol, alcohol or similar substances for cleaning
purposes. These could corrode the surface of the measuring device. Furthermore, the fumes are
hazardous to your health and explosive. You should also not use sharp-edged tools, screwdrivers, or
metal brushes or similar for cleaning.
75
Use a clean, lint-free, antistatic and slightly damp cloth to clean the device and display. Allow the
device to dry completely before using it for the next measuring task.
c) Opening the measuring device
For reasons of safety, it is only possible to replace the fuse and battery when all test leads have been
removed from the measuring device. The battery and fuse compartment cannot be opened when test
leads are plugged in.
In addition, when the housing is opened all measuring sockets are mechanically locked in order to
prevent the later insertion of the test leads. The locking will be automatically removed when the battery
and fuse compartment is again closed.
The housing is designed so that when the battery and fuse compartment is open only the battery
and fuses can be accessed. The housing does not have to be opened completely or taken apart any
longer. These measures increase the user safety and user-friendliness.
Proceed as follows to open:
1. Remove all test leads from the measuring device and switch
it off.
2. Loosen and remove the battery compartment screw (15) on
the back.
3. Fold out the positioning bracket (13). Pull the battery and
fuse compartment lid downwards from the measuring device
(Fig. 11).
4. The fuses and battery compartment are now accessible.
5. Close the housing in the reverse order and screw closed the
battery and fuse compartment.
6. The measuring device is again ready for use.

e) Replacing the button cell battery
If the date and time are no longer correctly displayed, the button cell battery must be replaced.
Proceed as follows to replace the button cell battery:
1. Remove the attached test leads from the measuring circuit and from your measuring device. Turn
off the DMM.
2. Open the battery and fuse compartment as described in Section “c) Opening the measuring device” (page 76).
3. Then loosen the four screws on the back of the device and carefully remove the housing.
4. Carefully push the button cell battery out of the battery holder from below. Lift the battery holder
slightly upwards while doing so.
5. Replace the used button cell battery with a new one of the same type (CR2032). Insert a new
button cell battery into the battery compartment. Make sure that the plus pole points upwards.
6. Close the housing in the reverse order and screw closed the battery and fuse compartment.
You can order a suitable button cell battery using the following part number:
