Installing batteries / rechargeable batteries / button cell / radio module:

Note: When installing the button cell, hold the meter with the carbineer toward you, (upside down). This will prevent the battery from accidentally falling into the wireless card slot.

1) Insert button cell (included, 1 CR2032) in the battery compartment (+) side up. This is a buffer battery to hold memory when batteries are changed.

2) If equipped, insert wireless radio module ribbed side up, contacts up, label down until module engages.

3) Insert 4 type AA alkaline batteries, or 4 rechargeable into the battery compartment,

observe polarity. Do not mix battery types

4) Close the battery compartment. Push until a click is felt.

Note: When not using for a long period of time, upload the memory to a PC and remove the AA batteries. Do not remove the button cell.

Switching the Instrument on:

The first time a new instrument is powered or when the batteries are replaced, the unit requires a general configuration including the language, battery type and date and time. After these parameters are set, they will not need to be adjusted until the batteries expire.

First time power up or after batteries are replaced.

Initial Unit configuration

The 556/560 requires initial configuration of the units of measure. Once configured, these parameters are stored in memory and will not need to be changed again unless the button cell is removed for an extended period of time. Changing the main batteries will not affect these settings.

Setting Relative or Absolute Pressures and Nulling (zeroing the sensor)

Use this menu to configure for relative or absolute pressure measurement. Relative pressure refers to standard atmospheric pressure, 0 psig at sea level; absolute pressure is 14.7 psia at sea level. After the pressure type has been selected, remove any hoses if installed and null the pressure sensor

From the measurement menu

1) Press the Menu key

2) Menu: Pressure Nulling (Zeroing) relative/absolute is displayed

3) Using the arrow keys scroll up to select relative or absolute pressure
