KEY DIFFERENCES BETWEEN
THE NEW ADM-870C and THE ADM-870
|
| RS232
TO PORTABLE PRINTER |
| The new
ADM-870C has an RS232 port that may be used with a portable printer. The
optional printer and cable can download each reading as it is taken, or
the entire contents of the memory can be downloaded and printed all at
once. |
| |
| RS232
TO COMPUTER |
| The RS232
link may be used in conjunction with WinWedge® software and a computer
to load readings directly into a spreadsheet format for display,
analysis, and manipulation. Data may also be downloaded into a word
processing format. The WinWedge software comes complete with an
instruction manual, license, CD, and full user support for WinWedge from
the manufacturer, Tal Technologies, Inc. www.taltech.com. |
| |
|
DISPLAY |
| The
ADM-870C has a new display that allows more information to be displayed.
It is also easier to read. |
| |
|
BACK-LIGHT |
| The new
display has a back-light for use in low-light conditions. The back-light
is turned on and off by toggling the ON/OFF key. Note that use of the
back-light significantly increases the load on the batteries and reduces
the operating time (measured by continuous reading operation) by about
half. It is difficult in normal light to tell if the back-light is on or
off. The meter will occasionally display a LIGHT ON message to caution
against unnecessary use of the back-light. The colon normally found in
the third position from the left of the displayed reading will be
replaced by two stacked ‘L’ symbols. |
| |
| OFF
KEY |
| The
addition of the back-light feature required a change in the way the
meter is turned off. To turn the meter off, press SHIFT, then OFF. |
| |
|
SPEED-READ |
| The SPEED-READ feature has been replaced by the
TREND mode. The TREND mode offers a continuous series of readings at
intervals of about once per second. The accuracy specifications do not
apply in TREND mode. |
| |
|
BATTERY CHARGE INDICATOR LIGHT |
| A green
LED on the front panel lights when the battery charger is properly
connected. |
| |
| STORED
READINGS |
| The
reading sequence number is displayed during a sequence of stored
readings. |
| |
| STATUS
DISPLAY |
| All
selected functions (measurement mode, units, local or standard
temperature) may always be read by pressing SHIFT/SHIFT. No reading is
taken, and no data is discarded. |
| |
| STORED
READING DELETION |
| Any
reading in a stored sequence may be deleted or replaced. The new sum and
average for the revised sequence will be calculated and displayed. This
replaces the prior method of using the RCL keys to delete the last
reading taken. |
| |
|
FLOWHOOD MODE SUMS AND AVERAGES |
| The
averages and sums of stored FLOWHOOD mode readings are now displayed
three different ways: all readings in sequence, backpressure compensated
readings, and nonbackpressure compensated readings. When the STORE key
is pressed repeatedly following a reading, the first display is the
average of all of the readings in the sequence combined, followed by the
average of just the compensated readings, and then the average of the
noncompensated readings. Pressing the STORE key repeatedly again will
display the sum of all the readings in the sequence, then the sum of the
compensated readings, and finally the sum of the noncompensated
readings. |
| |
|
POWER-ON DEFAULTS |
| The meter
will initialize with the mode and units which were selected when it was
last turned off using the meter keypad. This information will not be
saved if the meter was forced to shut down automatically due to low
voltage or excessive temperature or has been reset. |
| |
| CALC
DISPLAY ELIMINATED |
| The
ADM-870C uses a much faster microcontroller than the ADM-870.
Calculations occur almost instantaneously. There is no need to display a
CALC message. |
| |
| LOW
CHARGE DISPLAY |
| When the
battery charge is nearly depleted, the meter will display LOW CHARGE
periodically. The colon normally shown following the units for a
displayed reading will be replaced by a symbol for an empty battery
cell. |
