Checkline RTM 20D - Manual (Page 10)

6:1:4 UNIT Alternative Unit
The UNIT- button is used to change between normal unit and alternative unit.
The alternative unit mode is indicated by a flashing colon : on the left side of the display.
The RTM can e.g. have normal unit in ton and alternative unit in kN.
To get the tension displayed in the altenative unit, the electronics multiply the normal
reading by a programmed factor. The factor can only be changed in the calibration
mode.
If the UNIT is held in for about 2 seconds, the display will first indicate the present
"Rope No" for 2 seconds and then the battery voltage, until the button is released. This
is indicated by that the LOBAT indicator is lit and the och prefix “b” is viewed before the
voltage, e.g. .
6:1:5 Low Battery Voltage
The battery voltage is continuously measured and the LOBAT-indicator will lit up when
the voltage drops below approx. 7.0V. At that point you will have a maximum of two
hours of operation left from a lithium-battery (or app. 1 hour from an alkaline battery).
If the battery voltage drops to low (app. 5.6V), an error message will be displayed for
about 4 seconds and after that the unit is turned off automatically. This ensure
correct function during measurig. Change battery.
6:1:6 Select "Rope No"
The RTM 20 D can have up to 10 different calibrations (10 different type of ropes)
These are stored in positions called "Rope No" - 1 -, - 2 -, .....- 9 -, - 0 -.
You have to select the right "Rope No" for your measurements, look at the line list.
If you want to use last used "Rope No" you just turn on the RTM with the ON/OFF-but-
ton.
If you want to select another "Rope No" turn on the RTM according to:
PEAK + ON/OFF. The display will indicate last used "Rope No" e.g. .
Use the PEAK button to increase or the UNIT button to decrease until the preferred
number is displayed.
Only the programmed and calibrated "Rope No"s will be available. The "Rope No" and
corresponding rope type are presented in the rope list attached to the instrument.
