Description
The Charleswater Combo Tester is a 3-state touch tester
designed for fast, frequent testing of ESD personnel
grounding devices. The Combo Tester incorporates a
unique dual test circuit design which improves accuracy of
testing and eliminates the need for separate wrist strap and
foot grounder test units. The 99000 is equipped with a 750
Kilohm - 35 Megohm circuit, ideal for testing of wrist straps
and footwear.
Test parameters are factory set but can be adjusted to
match your own specifications. The Combo Tester is
very simple to operate. A green light signals the user that
everything is OK. A red light and an audible indicator means
that the circuit resistance is either too low or too high.
The testers each include a 80020, which
converts the banana plug on the face of the
unit into a 10mm snap. NOTE: Once the
80020 has been put into the plug socket, it
cannot be removed.
The tester operates on either a 9 volt battery or a special
AC adapter. The combo tester is available in two models:
the tester alone, or the tester with a stand. A footplate is
also available for use with the 99000 .

Installation of Model 99000
The Combo Tester may be used as a portable unit, or may
be permanently mounted on either a table or a wall. Please
refer to the following instructions when installing your tester.
Stationary Installation
If you will be using the tester as a portable unit, you may
prefer to mount the unit to a table or wall. Three keyhole
slots on the back of the unit are included to allow you to
attach the tester to a stationary surface.
Figure 2. Mounting hole locations
1. Select location for mounting tester. Install three #6 or #8
screws spaced as illustrated in figure 3, into a wall or other
vertical surface. Make sure that the screw heads do not
project out more than 6.35 mm from mounting surface. The
template on page four is actual size.
2. Mount the tester on the screws, pulling down to lock it in
place.

Operation
The Combo Tester can be operated either on battery or
AC power. The unit comes equipped with a 9 volt alkaline
battery. For AC operation, plug the optional AC adapter into
the mini phone jack located on the upper left hand corner of
the tester. An AC adapter is sold separately as item number
99065 (220 volt).
LOW BATTERY INDICATOR
The Combo Tester includes a low battery indicator alarm
circuit. If both the audible alarm and indicator LED turn on
during use, discontinue testing and replace the battery.
The tester will continue to operate with a weak battery, but
results should not be considered accurate.
The battery can be easily replaced by removing the battery
compartment cover on the back of the unit and installing a
new 9 volt battery.

General Instructions
In the following test configurations, the 99000 can be used
to test wrist straps while they are worn. Model 99004 will
also allow the user to test footwear.
WRIST STRAP TESTING WITH MODELS 99000
This test safely checks that a continuous path between the
operator, wrist strap and ground cord exists.
1. While wearing the wrist strap, plug the banana plug end
of the cord into the jack on the face of the unit.
2. Press rocker switch toward “WRIST CORD”.
3. Press the test button so that the unit activates. Hold
down for 2-3 seconds.
Note: DO NOT TOUCH ANY OTHER METAL WHILE
PERFORMING TEST.
Figure 5. Testing of wrist strap grounding assemblies
4. Lighting of the green “PASS” LED indicates that the wrist
strap and ground cord assemblies are functioning properly.
5. If either red “FAIL LO” or “FAIL HI” LEDs light and the
audible indicator sounds, the wrist strap wearer should
check the wrist strap assembly immediately.
TESTING FOOT GROUNDING DEVICES
In order to test footwear you will need the model 99000 with
the 99013 footplate, or the 99004. The following instructions
are intended for use while wearing foot grounding devices.
When testing conductive shoes, or foot grounders worn
on both feet, test each foot separately to ensure proper
operation and complete protection.
1. Place the Foot Plate on the floor in front of the Combo
Tester.
2. Plug the plate’s ground cord into the jack on the left hand
side of the unit.
Figure 6. Installing ground cord to “footplate” jack
NOTE: Steps A and B are not required with the 99004.
3. Place the rocker switch toward “FOOTPLATE”.
4. Place one foot on the plate. If the floor is conductive, lift
the foot you are not testing off of the floor during this test.
Make sure there is no cord plugged into the “WRISTCORD”
jack.
5. Press the test button so that the unit activates. Hold for
2-3 seconds.

The 99004’s rugged steel pedestal tube is powder coated
in a non-conductive white finish that helps to prevent false
readings if contacted by skin or loose smocks.

connector to the included 9 volt battery. Attach poster to the
wall at eye level in front of the tester location.
4. Install the tester on the bracket by aligning keyholes on
the back of tester with mounting studs on bracket. While
pushing up on thumb screw, insert the mounting studs into
the keyholes and slide the tester down. See figure 10.

Calibration
The models 99000 and 99004 are calibrated to factory
standards. We recommend that calibration is performed
annually to ensure that the Tester is operating within limits.
Due to its dual circuit design both test circuits of the Combo
Tester must be calibrated individually.
Charleswater offers a calibration unit that is specifically
designed to simplify the calibration procedure. This unit
comes calibrated to factory standards. For additional
information on the 99090, ask for Technical Bulletin
PPE-5034.E.

Figure 15. Calibration of the Combo Tester 750K to 35M
range with the model 99090
To calibrate, simply test each resistance value shown
above which are included in the 99090 Calibration Unit.
Test across the test button and “WRIST CORD” jack for
calibration of the 750 Kilohm - 35 Megohm range. Test
across the test button and “FOOTPLATE” jack for calibration
of the 750K - 35M range. Be sure rocker switch is set
correctly.
Observe the LED’s for the proper response as indicated. Be
sure to hold the cord at an insulated point, so that resistance
value is not affected by the body. Should testing reveal that
the Tester is not functioning properly, verify that the battery
or power supply is operating correctly.
Tester calibration can also be verified with the use of
discrete resistors and two banana-to-alligator cords.
Adjustment
Detailed adjustment instructions are available from the
factory. Unauthorized modifications will void the product
warranty. Servicing should be performed only at the factory.
See warranty section for repair information.
