GETTING
STARTED
The meter has no power-on
switch, so it will be in operation as soon as you apply power.
If you power
off/on the meter, it displays "RST", followed by a scrolling display
of "THERMISTOR" , followed by "Vxx" (designating the version
number, xx stands for the current version). Write down this version number
as you will need it if you telephone Customer Service.

LABEL
This label is located on top of the meter housing.
CHECKING MAIN BOARD POWER JUMPERS (Factory Set)
To check voltage jumpers,
or to change from 115 V to 230 V ac:
1.
Remove the main board from the case. Refer to Section 2.7.
2. Locate the solder jumpers W1, W2, and W3 (located near the edge
of the main board alongside the transformer - refer to Figures 3-1).
3. If your power requirement is 115 Vac, solder jumpers W1 and
W3 should be wired, but jumper W2 should not. If your power requirement
is 230 Vac, solder jumper W2 should be wired, but jumpers W1 and W3
should not.
NOTE: W4 jumper is not used.
Figure
3-1 shows the location of solder jumpers W1 through W3.

S2 jumpers and TP1
through TP6 (test posts) are used for calibration purposes only. Do not
change.
S3 jumpers are used for the following (refer to Table 3-1):
* To enable or disable the front panel push-buttons
* To allow for an extremely low resistance load for analog output
* To disable the MENU button
* To perform calibration procedure

DESCRIPTION
|
|
S3-A
|
Install
to enable front panel push-buttons. Remove to disable all front
panel push-buttons
|
|
S3-B
|
Removed.
Install for meter calibration.
|
|
S3-C
|
Normally:
Removed. Install for analog voltage output when load is less than
1 Kohm impedance. Care should be taken when installing this jumper,as
there is the possibility of oscillation.
|
|
S3-E
|
If installed without S3-B, MENU locks out. If
you press the MENU button, the meter shows "LOCK".

CONNECTING
MAIN POWER
Figure 3-3 shows the
proper ac main power connections:
WARNING:
Do not connect ac power to your meter until you have completed all input
and output connections. Failure to do so may result in injury!

MOUNTING
THE METER
1. Cut a hole in your panel, as shown in Figure 3-7.For
specific dimensions refer to Figure 3-8.
2. Insert the meter into the hole. Be sure the front bezel
is flush to the panel.
3. Proceed to Section 3.6 to connect your sensor
input and main power.
