SIMRET 4000 INSTRUCTIONS 

GETTING STARTED 

The Simret 4000 is operated by a single 

Click

 control. The central OK button may be 

single-clicked

double-clicked

, or 

held-down

. The surrounding arrow buttons are used to navigate menus by 

moving a 

 highlight

  bar

 

through a menu of options on the instrument’s display screen. Clicking the 

OK will select the highlighted item. Normally this will be accompanied by a beep from the 
instrument. The scroll bar on the right hand side indicates the relative position of the item within the 
menu. 
Whenever possible the instrument operates to these simple rules:  

 

single-click

 to choose a menu item 

 

single-click

 to return 

 

double-click

 to enter a 2

nd

 level menu  

 

single-click

 to return 

 

hold-down

 (for more than one second) to abandon a course of action  

 

Use

 or 

 to increase or decrease a value.  

 

Use the arrow buttons to scroll through a menu 

 

the last option of a menu will return you to the previous menu, or use the

 button. 

 

SWITCHING ON:

 To power the instrument, 

hold-down

 OK and then release. The display will 

appear when OK is released. The instrument will perform a short self-test and display its 
software version and when calibration is next due. The 

Start Menu

 will then appear.  

 

The self-test will warn if re-calibration is overdue and if more than 80 tests have been stored 
in memory. Upload or print the tests if the memory is getting full, then erase to create more 
space. If the SD card is fitted, tests will be backed-up automatically to create space. 

SWITCHING OFF:

 To manually switch off,

 hold-down

 OK in the 

Main Menu. 

If the control has 

not been operated for about 4 minutes, the instrument will switch itself off unless it has been 
armed for a test. It will also turn off if its battery is very low.  

EDITING: 

A built-in editor allows certain number values, names and software switches to be edited 

in the instrument. First highlight the item then for:
