Getting Started

Prior to initial set-up, check whether the batteries have been installed correctly in the device.
Inserting batteries

1. Open the battery compartment cover.
2. Insert battery making sure that the poles of the battery are in the right position
3. Close the battery compartment cover.

Only use type AA batteries!
Remove the batteries if the instrument is not used over a longer period of time.

Operation

Switching On/Off
On:
Press the “On/Off switch” to switch on the gradient module.
Off:
Press the “On/Off switch” for at least 2 seconds to switch off the gradient module.
Display
If the gradient spirit level is used in the inverted position (upside down – above your head), the display screen turns too so that the measurement can be read easily.
The display switches off automatically after 5 minutes, as soon as the device is no longer being moved.

Acoustic signal
By pressing the display circuit°/mm/m/%/in /ft/on/of switch acoustic (signal at 0 °and 90 °) for more than 2 seconds the acoustic signaling is switched on. The closer the gradient spirit level gets to the standard position, the more rapid the frequency of the acoustic signal. This function assists you with leveling work, where it is not possible for you to read the measurement from the display.

Hold function
The current measurement is frozen by pressing the “Hold function” once.
A previously measured value can be “frozen” on the display using this function.
The measurement remains unchanged until the “Hold function” button is pressed again.
Toggling between ABS and INC
You can toggle between ABS (absolute) and INC (incremental) by pressing the “Hold function” for more than 2 seconds.
In the “ABS” (absolute) mode, the measurement result is displayed based on the device calibration.
In contrast, in “INC” (incremental) mode, the measurement result is displayed based on a relative reference level.
For example, you can take a measurement on a 5° inclined plane in “ABS” mode and then toggle to the “INC” function. In doing so, the measurement display is set to 0°. You can now take additional measurements based on this new zero value. To leave “INC” mode, press the button again for 2 seconds.

Changing measurement display

• Press “Mode button° / mm / m /% / in / ft /on / off switch acoustic” (Signal at 0 ° and 90 °) to switch between ° / mm / m /% / in / ft.

Changing the display resolution
Press the “Hold function” and the “On/Off switch /Display light” button at the same time to change the resolutions between: 0.00° and 0.0°.

Bluetooth
Fast and efficient data transfer of measured values can be made directly to a smartphone via Bluetooth.
NOTE
To pair with a smartphone, launch the Hultafors measures app and connect using one of the function options.
