3.2 Duration of Display – Continuous operation

If for approx. 4 minutes none of the keys of the MAVO-MONITOR is pressed, the instrument will be

switched off automatically. During the last 4 seconds before automatic switch off an acoustic signal will

sound. By pressing any one of the keys, you can override the automatic switch off. When the instrument is

switched off, the values stored in the data memory and also the preset individual values will be maintained.

You can override the automatic switch off, when switching on the instrument and simultaneously keep the

HOLD key depressed.

The measuring unit (cd/m² or fL) in the display will blink and indicate that the continuous operation mode is

on.

4 Using the MAVO-MONITOR

4.1 Switching on – Making Measurement

Press the on/off key and the MAVO-MONITOR is immediately in the measuring mode and is measuring at

the rate of 2 times per second. The instrument is in the function „AUTO“, i.e. the MAVO-MONITOR will

select the best suited measuring range for the existing light level. By pressing one of the range keys, one of

the measuring ranges can be locked. Browsing up or down through additional measuring ranges is

accomplished by briefly pressing one of the range keys. If both keys are pressed and held simultaneously,

the instrument is returned to „AUTO RANGING“.

4.2 Selecting the desired measurement unit cd/m

or fL

Use the key cd/m

fL to select the desired unit for the read-out – cd/m² or fL.

4.3 Overload Display

When exceeding one of the measuring ranges „OL“ (Overload) appears in the display.

4.4 Memory Functions

The MAVO-MONITOR is provided in addition to the „Display Hold“ also with a memory for data up to 100

measurement values.

This function allows several measurement operations in the field and read-out at a later time. The data

stored in the memory will be maintained, even when the instrument is turned off or the battery is changed.

4.4.1 „HOLD“ Display Hold Function

The display HOLD function allows you to measure even at very low light levels, where it would be difficult to

read the display. By pressing the HOLD key, the last value measured is held on the display to be read at

brighter light. Pressing the HOLD key again will return the MAVO-MONITOR to the measuring function.

The function HOLD is the basic function for all the memory functions.
