OPERATING INSTRUCTIONS
-USER GUIDE-
This guide provides step-by-step instructions on powering up, using and powering down
the meter.
NAVIGATION:
The meter uses an on-screen, menu-driven approach to navigate through the meter
features, allowing for an intuitive understanding of keypad functions. Each screen
presents the user with a number of selectable options. One of the options is always
selected and the user can move (navigate) the selection to any other available option.
The keypad is aimed at providing navigational control, and not at accessing specific
features. There are four directional keys aligned intuitively around a middle (fifth) key
(see Figure 1): Above (UP), below (DOWN), to the right (RIGHT) and to the left (LEFT).
The middle key is used to SELECT the option highlighted on the screen. For purposes
of this owner’s manual, the five keys will be referred to as     and SELECT.
Fig. 1 Keypad Layout
INSTALLING THE BATTERY:
The battery compartment is located on the underside of the case, at the bottom of the
handle.
1. Open the battery compartment by sliding the lid back while pressing on the release
indent.

Copyright 2006, Delmhorst Instrument Co.
Page 6 of 32
2. Ensure correct polarity, and push the battery in flush with the bottom board until the
connectors snap together on both sides. Use only Duracell or Energizer alkaline
9V.
3. Replace the battery compartment lid.
IMPORTANT NOTE:
DO NOT REMOVE THE BATTERY WITHOUT TURNING THE METER OFF FIRST.
BATTERY REMOVAL WHILE THE METER IS ON MAY CAUSE LOSS OF STORED
READINGS AND MAY CORRUPT THE STORAGE MEMORY. IF THIS OCCURS,
CERTAIN FUNCTIONS (SUCH AS STATISTICS, READING RECALL, ETC) WILL FAIL
AND LOCK UP THE METER. If the battery is removed by accident while the meter is
ON, and if the readings already stored are important, DO NOT store additional readings.
Turn the meter back on and perform a PC download. Beware that any readings stored
during the power cycle that included the battery removal WILL NOT be available and
CANNOT be recovered. Once the download is complete, perform a meter reset by
choosing “RESTORE DEFAULTS” in the Storage Menu. If a download is not necessary,
go directly to “RESTORE DEFAULTS”.
LOW BATTERY:
The meter features a battery status monitor, designed to warn the user as well as protect
measurement accuracy from impending battery failure conditions. The battery warning is
triggered by either continuous or temporary low voltage conditions. Visible (a battery
icon on the top right side of the display) and audible (buzzer warble) indicators
accompany a battery warning.
Once a permanent low battery condition is detected, all measurement functions are
disabled. Enough power remains for other menu functions, including a PC download,
although almost any user action at this time causes a low-battery warning to be
generated. The battery should be replaced immediately. If the battery reaches critical
levels, the meter will refuse to stay on at power-up.
This gradual warning system is intended to provide the user advanced battery status
notice and give ample time for replacement before operational limitations occur.

METER USE
BASIC AND ENHANCED MODES:
TotalCheck may be used as a BASIC meter, which allows the user to begin taking
readings in either the scan mode or pin mode, without having to set up a job definition.
BASIC mode does not allow for data collection and is the default mode of the meter
upon power up.
Or, TotalCheck may be used in ENHANCED mode, which requires the user to set job
definitions and materials for each location within a job. The meter also stores each
reading in ENHANCED mode to allow for on screen reading recall or download to a PC.
USING THE METER IN BASIC MODE:
TotalCheck is shipped from the factory set to BASIC mode. Use this option if you wish
to use the meter for scan or pin readings without having to set up a job.
Although Basic Mode does not allow for data acquisition, it does allow the user to set the
type of material being tested, and set the alarm to sound if a pre-established %MC is
exceeded.
TO TAKE PIN READINGS IN BASIC MODE:
1. From the BASIC Main Menu, use the  key to highlight PIN MODE. Then,
use the SELECT key to enter the pin mode.

Page 19 of 32
A selected job containing readings offers two other selectable options: “VIEW SET” and
“DONE”.
oVIEW SET: This option allows the user to view a specific range of readings in a
particular job, as opposed to the entire set, by providing a configurable start point. It
becomes useful when large numbers of readings are present in the meter. View Set
always begins by displaying “1 TO XXX”, where XXX is the maximum number of readings
in the selected job. If left unchanged, the first reading to be reviewed will be number 1.
Readings may only be reviewed in ascending sequential order.
Using the   keys, the left-side value can be changed in increments of 10. For
example, assume the selected job contains 23 readings. The View Set entry will begin by
displaying “1 TO 23”. Successive Right button presses will yield the following: “11 TO 23”
and “21 TO 23”. At this point, the value on the left side is within 10 readings of the value
on the right side. Alternately, pressing the Left button causes the meter to subtract 10
from the current left-side value.
o DONE: Selecting this option signals to the meter that the user has completed the reading
recall setup process and is ready to begin reviewing readings.
NOTE: There may be a significant delay while the meter processes the required set of readings
for review, depending on the number of jobs present in the meter, percentage of memory space
occupied by readings, current job size and fragmentation. The meter will display a screen with the
word “PROCESSING…”. User input is ignored during this time. Control is returned to the user
once the algorithm is complete and the Retrieved Readings screen is displayed, as shown in the
example above:
o CANCEL: This feature returns the meter to the Storage Menu
•CLEAR MEMORY:
This option will delete all the readings stored in the meter, but will keep the
defined job structures and associated locations and areas in tact.
RESTORE DEFAULTS:
This will delete all defined parameters and readings stored in the meter. The
meter will be now set to the factory parameters: T = 70F, Non-insulated probe,
Backlight = OFF, Power-off time = 2 min.
Note: Memory deletion and restoring defaults are both irreversible.
