30. hFE This symbol indicates the transistor test.
31.1., 2. and 3. Sub-Display
These three small sub-displays with 4

digits are activated during
the different function modes.
32 = Low Battery
When this symbol is displayed, it is time to change the battery
33. Different Units of the Display Values
4. Use of the Multimeter
4.1 Inserting the Battery - Battery Exchange
To guarantee precise measurement, insert a standard 9 V battery. If the
battery symbol appears in the display, it is time to change the battery.
Proceed as follows:
disconnect your measuring unit from the measuring circuit
disconnect the test-leads from the measuring unit and turn off the
power.
remove with a crosspoint screw driver the fastening screw to open the
battery compartment.
now lift the cover carefully.
separate the old battery from the battery snap and fasten a new one
of the same type.
after the battery has been changed reinsert the battery into the batte-
ry case and close it carefully
secure it with the screw.
be careful that the battery leads (red/black) are not pinched between
the housing and the cover.

16. Overload "OL"-Indication
"OL" is displayed and an acoustic signal is emitted when the range is
exceeded = overflow (no acoustic signal during resistance measure-
ment, diode test or temperature measurement).
Attention!
Observe the max. input limits.
17. Data Hold D-H
Data Hold means the meter will "freeze" a display reading.
18. A-H "Auto-Hold" = Min, Max and AVG holding with simultaneous
display
19. REL = Relative = Reference Value
20. MEM = Memory = to memorize the value
21. RCL = Recall = to get back the memorized reading on the display.
22. CMP = Comparison = Compare a Reading
23. Reference No. (0 to 9)
24. / = Diode Test and acoustic continuity check
25. AC = Symbol for AC current or voltage
26. " - " = Minus Sign or Symbol for Negative Polarity
27. FREQ = Frequency
this symbol is displayed in the frequency count mode
28. TEMP = Temperature
This symbol is displayed during temperature measurement.
29. CAP = Capacitance
CAP is for Capacitance => Measurement of capacitors
