Field Correction (Menu Function); Temp. Correction (Menu Function); Remote Access (Menu Function); Remote Baudrate (Menu Function) - Magnet-physik FH 54 Operating Instructions Manual

Gauss- / Teslameter FH 54
If the function is activated, REL is shown in the lowest line of the display.
By pressing the Relative key, a dialog for the configuration of the Relative function is invoked.
With On and Off the function is activated or deactivated. Set allows to define the setpoint. If
Set is selected, the actual reading shown. It can be accepted as setpoint by pressing Enter or, by
using the keys, another value can be entered.
You can check for the actual setpoint by using the Show command.
The relative feature also interacts with other features. When Relative and Max Hold functions
are used at the same time, the relative reading is still in the top display, but the second line
shows the relative maximum instead of the relative setpoint.

5.13 Field Correction (Menu function)

In this menu the use of the correction tables for probe linearity and temperature dependence can
be switched on or off. Of course, therefore suitable correction data must be present in the probe
eeprom.
Many probes have, to enhance accuracy, a linearity correction table stored to the probe eeprom.
The choice "Field correction off" makes the FH 54 to ignore this table. Only the mean
sensitivity, that is also stored to the eeprom is used for calculation.
If a probe is connected to the FH 4, or if the instrument is switched off and on again, all
correction functions, that have correction data available, are switched on automatically.

5.14 Temp. Correction (Menu function)

Some probes contain a temperature sensor to correct for temperature dependence of sensitivity
and offset. This correction can be switched off in the menu Temp. Correction.
If a probe is connected to the FH 54, or if the instrument is switched off and on again, all
correction functions, that have correction data available, are switched on automatically.

5.15 Remote Access (Menu function)

After switching on the FH 54, the instrument is in local mode. The instrument can be operated
via the keypad. If the interface starts an access to the instrument it is set to remote mode and the
keypad access is limited.
To allow the keypad access again, the interface must receive the #LOCAL command or the user
must select the Local command in the remote access menu.

5.16 Remote Baudrate (Menu function)

Here the transfer rate for the serial interface can be set (4800, 9600, 19200 Baud). The number
of data bits is fixed to 8, the number of stop bits to 1. No parity bit is transferred.

5.17 Battery indicator

The battery indicator in the lower left corner of the display shows the remaining battery power.
It changes from for full batteries to if the batteries reach the end of their useful life.
Readings may not be as accurate when the batteries get low. The battery indicator works best
