With this function, two different operating modes can be read
simultaneously, e.g. the secondary voltage of a transformer < 125
VAC rms and AC power frequency
26. CMP = Comparison
27. "
" = Inductance
28. AC = AC voltage or current
29. (•) = Symbol for acoustic continuity tester
30. "-" = Minus sign and symbol for negative polarity
31. CAP = Capacity ==> measurement of capacitors
32. LOGI = Logic test
When the logic test function is selected, this symbol appears in the
display
33. Second "small" display for the DUAL display function
34. = Battery symbol
If this symbol appears in the display, the battery must be changed.
35. Various measurement units
36. Reference number: indicating the memory location numbering for
the MEM and RCL (=Recall) functions

5.4.2. Using the multimeter

A) Fitting the battery - changing the battery
So that the measuring instrument functions perfectly, it must be fitted
with a 9V battery. When the battery change symbol appears in the dis-
play (after approx. 60 hours of operation) the battery must be repla-
ced. To do this, proceed as follows:
The battery compartment is located beneath the upper cover (on the
rear of the case) which is secured with two screws, left and right.
Attention!
Remove the MS-9160 without fail from all circuits being measured befo-
re changing the battery.
Always switch off the instrument with the main switch (POWER), which
is located in the control area of the DC voltage power supply.
Only when it is certain that the MS-9150 is disconnected from AC
26
power and from all circuits should changing the battery be begun.
Screw out both crosshead screws carefully with a suitable screwdriver
and remove the cover cautiously. Remove the used battery (9 V). It is
connected with a battery clip. Remove this carefully from the old bat-
tery and connect the clip to a fresh, unused battery observing the pola-
rity. Push the battery into the battery compartment to the stop and
screw the cover carefully up again.
Attention!
Do not under any circumstances operate the measuring instrument
when it is open! Danger to life!
Leave no used battery in the measuring instrument, because even leak-
proof batteries can corrode and thereby release chemicals, which can
endanger health and destroy the battery compartment. Used batteries
are to be considered as special waste and must therefore be disposed of
without putting the environment at risk. Special collection containers
are provided for this purpose by specialist dealers and in scrap yards.
Switch the measuring instrument off when it is no longer required.
B) Connecting the test leads
Always use only the supplied test leads for making measurements.
Before each connection note the condition of the connecting plug and
test probes and check the insulation for damage.
These test leads are intended for voltages up to 1000 V max. The mea-
suring instrument is similarly designed for voltages up to 1000 VDC and
750 VAC rms max. Take particular care when dealing with voltages
greater than 25 V AC or 35 V DC.
Attention!
Never exceed the maximum input amplitudes, because danger to life
can arise under adverse conditions.
C) Putting into service
C.1 Basic settings
Press the ON button (1). The display is now illuminated. To select a fun-
ction, rotate the operating mode switch to the desired position. "Nor-
mal" measurements can now be performed without additional func-
