Hint
If you exit the function mode because you pushed the SET/R button too
often, this function mode is left, but the memory is not erased and can
be "recalled" with the following function mode.
g) RCL (= Recall)
This function enables you to get the memorized reading back on the
LCD. Follow these steps:
- Push FUNC key until RCL flashes. Push SET/R once. RCL is fixed but the
reference number flashes. Press UP or DOWN buttons to address the
desired number where the measurement has been memorized. Press
SET/R button to get the memorized value back on the display. Then
the chosen value will appear on the left sub-display. The following
memory locations are displayed in the other smaller displays. To exit
this function mode turn the function switch (observe the safety rules!)
or press the buttons FUNC or SET/R, afterwards return to basic set-
tings.
h) 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.At the same time an interval signal is emitted.
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
16
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 and Continuity Check
The value displayed is the forward voltage at approx. 1 mA test current.
Range of 0 - 2.0 V.
The contnuity test enables you to check continuity of wiring, connec-
tions or fuses. Either acoustic or visual test (display of measurement)
is possible. An acoustic signal is emitted at resistors below 30 Ω.
b) Negative Polarity
Shows if test-leads are confused or indicates negative input with a " - "
before the measurement.
c) FREQ Frequency Measurement
You can measure frequency up to 200 kHz.
d) TEMP Temperature Measurement
You can measure temperatures from -40°C to +1200°C with a thermo-
elemet (NiCrNi).
e) CAP Capacitance Measurement
The capacitance ranges lets you measure discharged capacitors of 10 nF
to 20 uF.
f) hFE Transistor Test
Enables you to measure the hFE value.
g) rDY = ready = Logictest
This function enables you to check and to display all usual logic levels.
h) Low Battery
A 9-Volt alkaline battery in this meter has an avery life of approx. 100
to 150 hours. Low battery indication approx. 8 hours before battery is
"dead". Battery check between the measurements.
