SECTION 8.0

TROUBLESHOOTING

8.4 TROUBLESHOOTING WHEN NO ERROR MESSAGE IS SHOWING — GENERAL

8.4.1 Difference Between Solut Comp II and Standard Thermometer is Greater than 3ºC.

A. Is the reference thermometer, RTD, or thermistor accurate? General purpose thermometers, particularly ones

that have been mistreated, can have surprisingly large errors.

B. Review Section 6.2.2.

8.4.2 Current Output Too Low.

Load resistance is too high. Maximum load is 600

Ω

8.4.3 Alarm Relays Do Not Work

Verify the relays are properly wired.

8.4.4 Display is Unreadable.

While holding down the MENU key, press

until the display has the correct contrast.

8.5 SIMULATING INPUTS — OZONE

To check the performance of the analyzer, use a decade box and battery to simulate the current from the sensor. The
battery, which opposes the polarizing voltage, is necessary to ensure that the sensor current has the correct sign.

A. Disconnect the anode and cathode leads from terminals 1 and 2 on TB3 and connect a decade box and bat-

tery as shown in Figure 8-1. It is not necessary to disconnect the RTD leads.

B. Set the decade box to the resistance shown below.

C. Note the sensor current. It should be close to the value in the table. The actual value depends on the voltage

of the battery. To view the sensor current, go to the main display and press

until the sensor current is dis-

played.

D. Change the decade box resistance and verify that the correct current is shown. Calculate current from the

equation:

current (nA) =

• 1000

The voltage of a fresh 1.5 volt battery is about 1.6 volt (1600 mV).

Problem

See Section

New temperature during calibration more than 2-3ºC different from the live reading

8.4.1

Current output is too low

8.4.2

Alarm relays do not operate when setpoint is exceeded
