2. Remove the clip-on foot cover by lifting up on the cover and releasing it from

the stabilizing arm at the bottom of the recorder. This exposes the rubber feet
and stabilizing arm. The rubber feet protect the bench top surface.

DO NOT ATTEMPT TO SET THE RECORDER UPRIGHT ON
THE BENCH WHEN THE CLIP-ON FOOT COVER IS IN
PLACE. THE RECORDER WILL TOPPLE OVER.

Figure 2-1. Foot Cover Removal

CAUTION

Clip

Cutaway View

!

3. Swing out the stabilizing arm and extend it towards you. Figure 2-2 shows how

to swing out the stabilizing arm. Make sure the slot in the stabilizing arm
extends out the rear of the recorder.

Figure 2-2. Swiveling Stabilizing Arm

When the recorder is in normal operating position (chart
door is closed), the stabilizing arm should be pushed to
middle position (the bumps on the arm will click in place
under the recorder). Refer to Figure
2-3a.

Before opening the chart door, pull the stabilizing arm out to
its full extension position to provide full stability. Refer to
Figure 2-3b. After closing the door, return the arm to its
middle position. Refer to Figure 2-3a.

Note that the arm extends towards the front or rear of the
case. If the unit is placed on a bench top snug against the
wall, extend the stabilizing arm fully to the front of the unit.
Refer to Figure 2-3b.

2.2 Mounting the Recorder on the Wall

To mount the recorder on the wall, first locate the wall mounting holes using the
template provided in the wall mounting kit. Leave the decorative foot cover
(Figure 1-1, item #18) in place*. After drilling the holes, insert the wall anchors
and put in the screws, leaving

1

⁄8 inch (3 mm) between the screw heads and the
wall. Hang the recorder by positioning the two (2) “keyholes” in the rear cover
over the screw heads.

* If the decorative foot cover is not in place, go through the following steps to

reinstall the cover (if desired):

1. Place the recorder on the table (so it is front face up).

2. Roughly position the foot cover so the clips are in line with the stabilizing
arm. Gently “stretch” the clips out and position over the arm as shown in
Figure 2-4a.

3. Once the clips are in place, gently slide down until the foot cover is even
with the front of the recorder as shown in Figure 2-4b.

2.3 Using Batteries

The recorder operates on either four “D” size non-rechargeable alkaline batteries
or a universal (100-240 Vac, 50-60 Hz) ac adapter.

In the event of ac power failure, the unit will switch over to
battery power automatically. Keep a fresh set of batteries in
the unit in case of power outage.

2.3.1 Installing Batteries

You may power the recorder with four “D” size alkaline batteries. Under normal
conditions, the recorder operates full time on battery power for up to three
months when using fresh alkaline batteries. When replacing batteries, we
recommend that you use Alkaline “D” size batteries for long life and for best
performance at low temperatures.

To install the batteries (refer to Figure 2-5):

The battery icon on the LCD shows the status of the batteries as shown below.

Figure 2-6. Battery Warnings

2.3.2 Connecting ac Power

The recorder can be ac powered using the universal 100-240 Vac adapter
supplied. The dc power jack is located on the right side of the unit (refer to
Figure 1-1, item #6.). The ac adapter provides 9 Vdc @ 1.7A power output and
comes with a 1.8 meters (6 ft.) long cable.

The following parameters are stored in the non-volatile
memory and will not be lost when batteries or main power
are removed

• Chart speed & scale

• High & low alarm set points for the two channel

• Chart Data points

When the recorder runs only on AC adaptor, and the main power restores after a
power failure, the recorder turns on automatically without pressing the Power
Key. All LCD segments turn on momentarily, then there is a 20 second delay
before the revision screen. This only happens when the power is removed
without pressing the Power Key. The pens go to the home position and back to
the correct chart scale everytime the recorder powers up.

2.5 Installing and Removing Pens

The recorder already comes with the two pens installed. While the unit is turned
off, open the recorder door and remove the pen caps from the two pens. Place
the pen caps on the two posts as shown in Fig. 2-11.

2.5.1 Installing the Pens

The recorder uses two different colored pens to record information. The red
(upper) pen records temperature. The blue (lower) pen records relative humidity.
Pen life varies with use and climate. Under normal operating conditions, pens
last at least one month. We recommend that you install a fresh set of pens after
every month of use.

To install pens:

1. Make sure the recorder is turned off. The recorder door should be closed.

2. Examine the location of the pen arms through the window in the recorder door.
a. If the pen arms are offset as shown in Figure 2-9, continue to Step 3:

(The pen arms must be offset sufficiently to allow for clearance before insertion
or removal of pens are attempted. The pens must be moved electrically.)

• Make sure the recorder door is closed and a piece of chart paper is

installed on the spindle on the chart base.

• Turn on the unit by pressing the power key and wait for the pens to be

far enough apart to remove a used pen one at a time or to insert a new
pen one at a time.

DO NOT ATTEMPT TO OFFSET THE PENS
MANUALLY (BY HAND). THE DRIVE MECHANISM
COULD BE DAMAGED. DO NOT ATTEMPT TO
CHANGE THE PENS WHILE THEY ARE IN
MOTION.

• Turn off the unit by pressing the power key again to stop the pen

movement.

3. Open the recorder door by applying downward pressure on the latch button.

4. Remove the pens from the package and the cap from each pen.

We recommend that you put the pen caps on special posts located on the chart base
of the recorder near the light bulbs. Figure 2-11 shows the location of the posts.

Figure 2-14. Setting Alarms and Time Clock

Press key to get into the Configuration mode. In this mode, you can set
High & Low alarm points as well as the Time Clock as shown in the flow chart
on the previous page.

You can exit the configuration menu at any time by pressing the key. The
high & low alarm set points are stored in the non-volatile memory. Removing
power (ac adapter or batteries) will not affect the alarm settings. The real time clock
has its own rechargeable battery back up. The clock continues to operate when the
main power is removed for about 14 days. There is no need to change the real time
clock battery since it gets charged every time the main power is present.

The recorder has two built-in Relays and provides an additional two voltage
outputs to drive external mechanical relays. There is a 10 position terminal block
in the back of the recorder. It provides the two relay contact closures & two
signal outputs to drive external mechanical relays as shown in Fig 2.14. In order
to do your wiring, remove the terminal block from the back of the recorder.
Connect your wiring, then plug the terminal block back in its place.

7

Figure 2-15. Relay Terminal Block Wiring Diagram

When the recorder is in alarm condition, the high or low alarm icon
and the channel no. flashes on the display. The unit beeps and the
corresponding relay output turns on (Built-in Relay energizes-contact
closure- and/or relay voltage output goes high). You can disable the
high or low alarms by going thru the configuration menu and
pressing the SET key to disable.
If you are switching inductive loads across Relay contacts, it is
recommended to connect a Varistor across the relay contacts to
protect the contacts from the rush current during the switching
period.
