4.1

Digital Display

The digital display (9) shows the measurement value with correct 
decimal point and sign. The selected unit of measure (12) and the 
current type (11) are also displayed. A minus sign appears in front 
of the value for zero-frequency quantities, if the positive pole of the 
measured quantity is applied to the “

” input. “OL” is displayed if an 

upper range limit of 3099 is exceeded (within

range: 1999).

The digital display is refreshed twice per second for the measure-
ment of V and 

Ω

.

4.2

Analog Display

The analog display with pointer demonstrates the dynamic charac-
teristics of a moving coil mechanism and is refreshed 20 times per 
second for V and 

Ω

 measurements. The analog display is especially 

advantageous for the observation of measurement value fluctua-
tions and for balancing.
The analog display has its own polarity indicator. The negative 
range of the analog scale (15) includes 5 graduations for the mea-
surement of zero-frequency quantities, so that fluctuations around 
zero can be observed. If the measurement value exceeds the dis-
play range the triangle at the left side (16) is first displayed, and 
then, after about 0.7 s, polarity at the analog display is reversed. 
Overranging (> 3099 digit, or  > 1999 in the

range) is indicated 

with the triangle at the right side (13).

Measurement Value Storage, “DATA”

 

Measurement values can be automatically “frozen” with the DATA 
function. This can be especially useful when contacting the mea-
suring point with the test probes requires your full attention. After 
the measurement value has been acquired and the appropriate 
“condition” has been fulfilled according to the following table, the 
measured quantity is frozen at the digital display and an acoustic 
signal sounds. The test probes can now be removed from the mea-
suring point and the measurement value can be read from the digi-
tal display (9). If the measurement value lies below the limit value 
shown in the table, the instrument is reactivated for the storage of a 
new value.
The DATA function has no effect on the analog display, from which 
you can continue to read the current measurement value. However, 
when the digital display has been frozen, the decimal point can no 
longer be shifted. Thus if automatic measuring range selection has 
been activated, you are no longer able to determine which measur-
ing range is active for the analog display. Manual measuring range 
selection is disabled, as long as the DATA function is active.
