ON

1. Connect power supply and switch AC on. Yellow power LED will
illuminate.

2. Wait for AMBER charging LED to stop ashing

3. When GREEN LED shows, connect calibrated multimeter and switch
to 20V DC range.

4. Connect battery tester clips tightly to posts, RED + BLACK -

5. During battery tester power up, allow multimeter voltage to stablise, then
compare voltage with battery tester. Pass equals ±5% of multimeter
reading.

6. Record battery tester Ah reading Pass = 7Ah - 9Ah

7. Replace battery tester leads if Ah reading is low or erratic. IMPORTANT:
BATMASTER operating temperature 20°C - 30°C (68°F - 86°F)
Replace BATMASTER internal battery (Yuasa NP7Ah-12V) when RED
LED indicates.

BATMASTER

Operation

BATMASTER works in conjunction with your own calibrated multimeter. It quickly compares

accuracy between the calibrated multimeter and ACT Intelligent Battery Tester under test.

It allows you compare DCV and verify Ah capacity. Readings within ±5% of the calibrated

multimeter will prove the ACT Intelligent Battery Tester under test is deemed accurate to

BS ISO9001 standards. For ACT RED/GOLD-IBT Intelligent Battery Testers and GOLD PLUS

Intelligent Battery Tester models only.

1. Connect power supply and switch AC on. Yellow power LED will illuminate.

2. Wait for AMBER charging LED to stop ashing

3. When GREEN LED shows, connect calibrated multimeter and switch to 2OV DC range.

4. Connect battery tester clips tightly to posts, RED + BLACK -

5. During battery tester power up, allow multimeter voltage to stablise, then compare

voltage with battery tester. Pass equals ±5% of multimeter reading.

6. Record battery tester Ah reading Pass = 7Ah - 9Ah

7. Replace battery tester leads if Ah reading is low or erratic. IMPORTANT: BATMASTER

operating temperature 20°C - 30°C (68°F - 86°F) Replace BATMASTER internal battery

(Yuasa NP7Ah-12V) when RED LED indicates.

WHY IS MY GOLD PLUS READING LESS THAN 7Ah?

The BATMASTER contains a conditioned reference 7Ah SLA Battery. This is rated 7Ah at

20C. After longer periods without use, this capacity will, as all batteries, reduce over time.

Even slightly below room temperature will result in a lower reading being obtained. We

recommend leaving the BATMASTER connected to the mains for at least 24 hours before

using for the rst time, and if the BATMASTER has not been used for a period of more than

1 month.

Pass Rate Equals ±5%

Operating Temperature 20 - 30ºC (68 - 86ºF)

RED LED Indicates to replace BATMASTER battery (Yuasa NP7Ah-12V)
