Setup and Programming
There is
no need to recalibrate
the meter for frequency in Hz when first received
from the factory.
The meter is
factory calibrated
for Hz prior to shipment. The calibration
equipment is certified to NIST standards.
Overview
Setup and programming is done through the infrared through-glass buttons, or using the mechanical
buttons when uncovered. There are two slide switches located on the display module. One is used to
configure the input and the other is to lock or unlock the Through-Glass Buttons.
Through-Glass Buttons
The BERT-E is equipped with four sensors that operate as through-glass buttons so that it can be
programmed and operated without removing the cover (and exposing the electronics) in a hazardous
area. These buttons can be disabled for security by using the THRU-GLASS BUTTONS switch and
selecting the OFF setting. This switch is located on the back of the removable electronics module.
Through-Glass Button Operation
To actuate a button, press and remove one finger to the glass directly over the marked button area.
Remove finger to at least 4 inches away from the glass in between button activations. Through-Glass and
mechanical buttons may be held to cycle through menus or digits in place of repeatedly pushing a button.
Through-Glass Power Save Mode
Through-Glass buttons enter a power saving mode after three minutes of
inactivity. This mode is indicated by a pause symbol ( ) appearing in the lower
right of the display. Only the
MENU
button is monitored in this mode. To activate
the Through-Glass buttons, press and hold the menu button for up to five
seconds. The display will read
AWAKE
, and the Through-Glass buttons will be
fully enabled.
Through-Glass Disabled Mode
When the cover is removed, the four mechanical buttons located next to the
sensors may be used. The sensors are disabled when a mechanical button is
pressed and will automatically be re-enabled after 60 seconds of inactivity. The
Through-Glass power symbol ( ) will blink in the lower right of the display if the
buttons are disabled due to a mechanical pushbutton being pressed.
!
IMPORTANT
Through-Glass buttons will not work if two or more buttons are
detected as being pressed simultaneously. As a result, be careful
to avoid triggering multiple buttons or reaching across one button
location to press another.
