This loop is entered by pressing the "START TEST" button. After releasing "START 
TEST" the last measured value stays on the display. By repeated pressing of the 
"DISPLAY MENU" button all supplementary values can be called. If a measured value 
exceeds or falls below the pre-set limit, the limit can be displayed as well (with "DISPLAY 
MENU"). In that case the measured value is diplayed with a flashing "LIMIT" whereas the 
limit value is displayed with a steady "LIMIT"-symbol. 

Further possibilities of button operation: 

Warning sound () cancel with "DISPLAY MENU" (with display switchover) or with 
"CHANGE ITEM" or "SELECT" button (without display switchover). 

The instrument implements an automatic check, corresponding to the measurement 
selected, to see if the correct input sockets are used.  

The display symbols  and 

 

are assigned to a specific socket as shown in 

Figure 4. 

From the way the symbols are displayed, the validity of the connected wiring can be 
concluded by the following features: 

•

  socket incorrectly wired (or, by mistake, not wired): corresponding symbol flashes. 

•

  socket correctly wired: corresponding symbol is steady active 

•

  socket with no connection: corresponding symbol is blank 

This measuring function detects possible interference voltages and their frequencies. 
This function is automatically active in every switch position before an earthing or 
resistance measurement. If the pre-set limit values are exceeded, the interference 
voltage is indicated as too high and a measurement automatically prevented. The 
frequency of an interference voltage is only measurable if the level of this interference 
voltage is higher than 1 V. 

Bring central rotary switch in desired position, read out measured value of interference 
voltage, measured value of interference frequency is displayed with "DISPLAY".
