10. Additional Functions

The function buttons (G) can be used to activate various additional
functions. With the push of the button, an acoustic signal is output for
confirmation.

a) SELECT Function

Several measuring functions are assigned subfunctions. The subfunctions are marked red. Push "SELECT" to select
them. Every push will switch to the next subfunction.

b) RANGE - Manual Measurement Range Selection

The RANGE function permits manual setting of a specific measurement range. It is possible that the automatic meas-
urement range setting will already select the next-higher measurement range or switch between ranges if the range is
problematic. To suppress this, the measurement range can be set manually in some measuring functions. The manual
measurement range setting works only in the following measuring functions: V, Ω, µA, mA, A.
Pushing the "RANGE" button will cause the "AUTO" symbol to go out and the device to switch to manual mode.
Each push of the "RANGE" button switches the measurement range; at the end, it will start with the lowest measure-
ment range again. The respective measurement range is indicated by the position of the decimal point.
To switch off this function, keep the "RANGE" button pressed for approx. 2 s. The "AUTO" symbol appears and the
automatic measurement range selection is active again. Switching the measuring function deactivates this function
as well.

c) MAX MIN Function

This function permits saving and display of maximum or minimum values during a measuring series. Press the "MAX
MIN" button to activate this measuring function. Auto-range is deactivated.
With the active function, the minimum and maximum value of the current measuring series is saved at the same time.
The max. and min. display can be switched at every push of a button. The values are deleted after a measuring func-
tion change or when switching off the device.
To deactivate the function, keep the "MAX MIN" button pushed for approx. 2 seconds. The display "MAX" or "MIN"
disappears and "AUTO" appears again.

d) REL Function

The REL function allows a reference value measurement to avoid possible scatter displays or line loss as it occurs,
e.g., during impedance measurements. For this purpose, the current indicated value is set to zero. A new reference
value is set. Auto-range remains active but is no longer displayed.
Press the "REL" button to activate this measuring function. The display indicates "Δ".
In order to switch off this function, push the "REL" button again or change the measurement function.
The REL function is not active in the following measuring functions: LoZ-V, continuity test, diode
test, frequency (Hz%).
