acoustic or visual test (display of measurement) is possible. An acou-
stic signal is emitted at resistors below 40 Ohm.
c) Negative Polarity
Shows if test-leads are confused or indicates negative input with a “-“
before the measurement.
d) FREQ Frequency Measurement
You can measure frequency up to 40 MHz.
e) TEMP Temperature Measurement
You can measure temperatures from -40°C to +1200°C with a ther-
moelement (NiCrNi).
f) CAP Capacitance Measurement
The capacitance range lets you measure discharged capacitors of 4 nF
to 400 µF.
g) HFE Transistor Test
Enables you to measure the hFE value.
h) LOGIC Logictest
This function enables you to check and to display all usual logic levels.
i)
Low Battery
A 9-Volt alkaline battery in this meter has an average life of approx.
20 to 30 hours. Low battery indication appears approx. 8 hours befo-
re battery is “dead“.
j) The following symbols indicate the units of the value displays:
AC
= AC current or voltage
DC
= DC current or voltage
mV
= Millivolt (exp.-3)
V
= Volts
mA
= Milliampere (exp.-3)
A
= Ampere
W
= Watt
kWh
= Kilowatt hours
Hz
= Hertz
KHz
= Kilohertz (exp.3)
MHz
= Megahertz (exp.6)

recalled value (ref. no. 1) on the middle sub-display and 3rd recalled
value (ref. no. 2) on the right sub-display.
i) CMP (= Comparison)
This function mode enables you to make the High/Low comparison of
subsequent readings, by comparing a reading with both the stored
high reference value and the stored low reference value.
On the sub-display “Lo“ appears for reading less than the low refe-
rence value, “Hi“ is displayed for reading more than the highest refe-
rence value and “Pass“ for a middle value between the low and the
high reference value.
To activate this function mode, push “Func“ until the symbol “CMP“
appears on the top of the display and “LOW“ flashes over the left
sub-display. Now push again SET/R button and then “UP“ and
“DOWN“ to set the minimum reference value with polarity. Press
after each change SET/R button again, to enter the setting and to go
to the next digit. As soon as the minimum reference (MIN) value has
been fixed, “HIGH“ flashes over the right sub-display. Set this high
reference value respectively (with polarity and four digit value). After
the reference values have been defined press SET/R key again. Now
“R-H“ for Range Hold flashes in the top line of the display. Set with
the UP and DOWN buttons the measuring range (e.g. voltage control
in a circuit under worst-case conditions). After the measuring range
has been entered (as far as a manual selection is possible) Comparison
= CMP is activated.
To exit CMP mode turn the rotary function switch (observe the safety
rules!) to an adjacent range or press “FUNC“.
Reset with the SET/R button is also possible, even during measurement.
4.4.5 Display Annunciators and Symbols for the Modes
a) Diode Test
The value displayed is the forward voltage at approx. 1 mA test cur-
rent. Range of 0 - 2.0 V.
b) Continuity Check
Enables you to check continuity of wiring, connections or fuses. Either
