E/H - Pressing the E/H keypad toggles the operation mode
between Electric and Magnetic field indications. The current
measurement units are displayed to the right of the reading on
the LCD.
The E/H keypad is also used to adjust the display response time.
This is done just after the meter is turned on. During the self-test
routine, the display will show all segments lit. When all the
segments are lit, press and hold the MODE SELECT keypad to
enter the setup mode. Hold the MODE SELECT keypad until the
display reads "F-#" and the current H-field unit of measure.
Press the E/H keypad to scroll through the four display filter
settings. F-4 has the "fastest" response time, ie. the least
filtering. F-1 has the "slowest" response time, ie. the most
filtering. The difference in response from level to level is a factor
of 2. Experiment with the settings to find which response level is
best suited to your measurement requirements. Once the
desired units are selected, press the MODE SELECT keypad to
save the current setup, leave the setup mode, and begin normal
measurement operation.
The instrument will normally be received from the factory with the
display response filter set at F-2. The display response setting is
stored in the non-volatile memory of the HI-3603 and if the
setting is changed, the new setting will be saved and will become
the default condition.
We recommend that you check the display response setting
when you first receive the instrument and after battery
replacement. The display response setting does not affect the
accuracy of the instrument.
BATT - The BATT keypad displays the supply battery voltage
along with the battery symbol. The low battery indication will
begin to flash at about 7.5 volts. When the battery voltage drops
to 7.25 volts, the display will blank with only the BATT symbol
displayed and the batteries must be replaced.
