Temperature Measurement - Conrad M-4660A Bedienungsanleitung

Attention!
If this supply voltage is more than 20 VDC, a buzzer sound is emitted,
too and "OL" for Overload is displayed.
During logic measurement the measuring socket and the current termi-
nals must not be connected.
6. Now the multimeter is "ready" to check the logic level test points of the
circuit in question. Separate the red test-probe from the supplying
voltage point. Now move the red test-pobes to the points in question.
Hint
During logic-level measurement, the right sub-display will show the pre-
sent DC current value and the middle sub-display displays the frequency.

5.10 Temperature Measurement

Temperature is displayed on the main and the sub-display. The main display
will show the temperature in Centigrade, while the middle sub-display
will show the temperature in Fahrenheit. The temperature range is from
-40°C to + 1200°C. Temperature measurement is exclusivley executed
with K-type temp probes.
For temperature measurement proceed as follows:
1. Select "TEMP" with the rotary function switch.
2. Plug in the temp probe into TEMP/CAP socket, observe the correct
polarity (narrow and wide tongue). (Use both sockets before and
after the separation bar in the middle)
Attention!
Do not connect voltages. The unit can be destroyed. When measuring
temperature, do not connect voltage input terminal or the current ter-
minals.

5.11 Usage of the Analogous Bargraph
The bargraph is easy to use and to understand. Is is comparable with the
needle of an analogous measuring instrument, but without its mechani-
cal disadvantages. Is is especially for quick changing measuring signals,
for which the digital display is too "slow". So you can quickly recognize
see tendencies in the measuring values. The measuring rate is 3-4 mea-
surements/s.
5.12 CMOS Signal Output
The mulitmeter M-4660A is equipped with a kind of "Function Generator"
which supplies ten preset frequencies with a voltage of max. 3.3 V. To
"tap off" the signal insert the enclosed signal adapter into the capacitor
socket, observe the correct polarity. The other end of the adaptor has
two small alligator clips.
To change the multimeter into a signal generator and to select the output
frequency follow these steps:
1. Select S/O with the rotary function switch.
2. Connect the enclosed signal adapter (on one end with alligator clips)
with the capacity measuring socket of the multimeter.
3. Turn on the multimeter.
4. In the basic function mode the reference number is displayed in the
left sub-display, the main display will show the respective frequency
"0.010 KHz" (= 10 Hz). In the middle sub-display the respective signal
output voltage is displayed in "V"(0.0).
5. To select other output frequencies push either "UP" or "DOWN" button.
For frequency and connected reference number see below:
0.010 KHz = 10 Hz, reference no. 0
0.050 KHz = 50 Hz, reference no. 1
0.060 KHz = 60 Hz, reference no. 2
0.100 KHz = 100 Hz, reference no. 3
0.400 KHz = 400 Hz, reference no. 4
1.010 KHz = 1010 Hz, reference no. 5
2.021 KHz = 2021 Hz, reference no. 6
4.042 KHz = 4042 Hz, reference no. 7
8.084 KHz = 8084 Hz, reference no. 8
10.24 KHz = 10240 Hz, reference no. 9
