TROUBLESHOOTING

6.1

Introduction

Correcting problem conditions with the sens

ion

™

electrochemical meters is limited to responding to the error
message displayed. Other problems must be handled by a Hach
technician at a service center. Refer to Repair Service. Do not
attempt to service the meter as there are no field-serviceable
parts. Opening the meter case will void the warranty.

6.2

Shorting Test

This test detects the meter offset

1. Turn the meter on. Connect the shorting cap to the BNC

connector (see Figure 6). Select the BNC connector from

Setup 1

.

2. Change the output to display in mV (press the

pH/mV

key to

toggle between mV and pH). The display should show

0.1

mV

. If it does not, contact Hach Service.
