SETUP
CONDITIONS REQUIRING DISASSEMBLY
You
may need to open up the meter for one of the following reasons:
1. To check or change the 115 or 230 V ac power jumpers.
2. To install or remove jumpers on the main board.
DISASSEMBLY
Removing
and accessing the main meter board:
1. Make sure that main power has been removed from the meter
2. Remove the rear case cover.
3. Lift the rear of the main board upwards and slide out of the
case.

MAIN BOARD POWER JUMPERS
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 6.2.
2. Locate the solder jumpers W1, W2, and W3 (located near the edge
of the main board alongside the transformer - refer to Figure 6-1).
3. If your power requirement is 115 V ac, solder jumpers W1 and
W3 should be wired, but jumper W2 should not. If your power requirement
is 230 V ac, solder jumper W2 should be wired, but jumpers W1 and W3
should not.
NOTE: W4 jumper is not used.
Figure
6-1 shows the W1 through W3 jumpers on the main board.

S2
jumpers are for sensor break indications:
* S2A jumper is not used
* S2B jumper is for positive sensor break (i.e. heating)
* S2C & S2D are not used
S3 jumpers are used for the following (refer to Table
6-1):
* 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
Test pins TP1 - TP11 are for testing purposes. Do not
use as reading errors may result.
