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 equip-
ment is certified to NIST standards.
Overview
Setup and programming is done through the infrared through-glass SafeTouch ®
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 SafeTouch
® Buttons.
SafeTouch ® Buttons
The PD6830 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.
SafeTouch 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. SafeTouch and mechanical buttons may be held to cycle
through menus or digits in place of repeatedly pushing a button.
SafeTouch Power Save Mode
SafeTouch 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
SafeTouch buttons, press and hold the menu button for up to five seconds. The
display will read AWAKE, and the SafeTouch buttons will be fully enabled.
SafeTouch 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
SafeTouch power symbol (
) will blink in the lower right of the display if the
buttons are disabled due to a mechanical pushbutton being pressed.
IMPORTANT
SafeTouch 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.
