The default display response filter is F-2 (refer to KEYPAD
MATRIX in this section for more information). The instrument
will normally be received from the factory with this setting (F-
2). The display response setting is stored in the non-volatile
memory of the HI-3604 and if the setting is changed, the new
setting will be saved and will become the default condition. For
this reason, 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.
The battery condition is indicated by a small "battery" symbol
in the lower left corner of the LCD. As the battery voltage
decreases, the low battery symbol begins to blink. If the battery
condition is allowed to drop below that necessary for proper
operation, the display will go blank.
Digital Display
The HI-3604 uses a custom Liquid Crystal Display to provide
information on instrument setting as well as the variables being
measured. Refer to Figure 3-2 for the display outline.
Electric Field/Magnetic Field Mode Selection
The HI-3604 measures both electric (E) and magnetic (H) fields.
The unit is switched between the E and H field modes using the
membrane switch panel keypads. The units being measured are
shown on the LCD display.
